Ready Mix Concrete supplied across Goa in grades from M20 through M45, with high-strength grades such as M60 available on request — mix requirements and delivery coordinated to the project, produced at RMC batching plants operated by Sabsol Qualitech Industries LLP.
Ready Mix Concrete is specified by grade because the grade sets the structural strength the design relies on. OM Group supplies Ready Mix Concrete across North and South Goa, produced at RMC batching plants at Kundaim and Thivim operated by Sabsol Qualitech Industries LLP, with fresh concrete transported and delivered to site by transit mixer against the project's mix requirement and pour schedule.
RMC is not simply concrete delivered by truck — it is a controlled production and supply system. Raw materials are stored and proportioned at a batching plant to a specified mix design, mixed under quality control, then transported and delivered ready for placement, with consistency managed at the point of production rather than assembled on site.
The abbreviation RMC is used interchangeably with Ready Mix Concrete in Indian construction trade usage. IS 4926:2003, the Indian Standard governing RMC production and supply, sets out batching, mixing, quality control and delivery-documentation requirements for the plant-and-transport side of the process — it does not cover placement, compaction, curing or protection after delivery, which remain the contractor's responsibility on site.
RMC and site-mixed concrete can both meet the same specified grade — the difference is in how consistently that grade is met batch to batch, and what it takes on site to get there.
| RMC | Site-mixed concrete | |
|---|---|---|
| Batching | Controlled, plant-based | Manual or small-mixer, on site |
| Material consistency | Batch-to-batch controlled at the plant | Varies with site practice and crew |
| Labour requirement | Lower on-site labour for mixing | Higher — mixing is a site activity |
| Site space | Less storage needed on site | Requires material stockpiling space |
| Production scale | Suited to larger or continuous pours | Suited to small quantities |
| Scheduling | Coordinated delivery to the pour schedule | Flexible, but consistency depends on the crew |
| Documentation | Delivery ticket, batch record | Depends on the project's own QA system |
RMC can offer advantages where controlled batching, consistency and coordinated delivery matter — it is not automatically the better choice for every project scale.
Ready Mix Concrete supplied by OM Group is produced at RMC batching plants at Kundaim and Thivim operated by Sabsol Qualitech Industries LLP. The sequence below covers what happens from raw material through to discharge on site.
Steps 1–9 sit within RMC production and supply, governed by IS 4926:2003. Placement, compaction, finishing, curing and protection after discharge are site-side activities carried out by the project's own contractor, outside IS 4926's production-and-supply scope and outside OM Group's delivery responsibility unless separately agreed.
Cement and, where used, supplementary cementitious materials — the primary binder driving strength development and setting behaviour.
Sand or manufactured sand, filling the space between coarse particles and affecting workability, cohesion and finish.
Crushed stone carrying the bulk of the mix by volume, with grading affecting workability, packing and finished surface.
Hydrates the cement and contributes to workability — the water-cementitious ratio is a primary driver of strength and durability.
Used where the mix design calls for them, to modify setting time, workability or durability characteristics for the specific requirement.
Proportions each of the above against the project's strength, workability and durability requirement — not a fixed recipe applied uniformly.
No proprietary mix ratio is published on this page. Proportions are project-specific, set by the mix design against IS 10262:2019 — publishing a generic recipe without a project-specific basis would be inaccurate rather than merely unhelpful.
Mix design balances characteristic strength, target mean strength, water-cementitious ratio, workability, aggregate grading, cementitious content, admixture use, durability requirement and exposure condition against the project's actual specification, referenced against IS 10262:2019. It is not a calculator this page can substitute for — the requirement should come from the project's structural design.
M20 through M45 are supplied as standard. High-strength grades such as M60 are supplied on request, subject to project-specific mix design and confirmation. Select a grade to jump to its section.
Commonly considered for residential RCC, slabs, beams, columns and foundations.
Commonly considered where a higher durability or load requirement than M20 applies.
Commonly considered for commercial construction, structural RCC and infrastructure work.
Commonly considered for higher-strength structural applications in commercial and infrastructure work.
Commonly considered for high-demand structural applications across infrastructure and industrial work.
Toward the upper end of the standard-concrete range — considered for demanding commercial or industrial structures.
Specialised high-strength applications, subject to project confirmation and performance-based mix evaluation.
| Grade | Characteristic strength | Classification | Mix type | Typical context* | Availability |
|---|---|---|---|---|---|
| M20 | 20 MPa | Ordinary | Nominal or design mix | Residential RCC, slabs, beams, columns, foundations | Standard |

*Commonly considered for — not a prescription. Actual grade selection is subject to structural design and project specification.
M20 denotes a concrete grade with a characteristic cube compressive strength of 20 MPa at 28 days. It is classed as ordinary concrete under IS 456:2000, where nominal mix is permitted, though a project may still specify design mix at this grade. It is commonly considered for residential RCC, slabs, beams, columns and foundations. When ordering, confirm whether your specification calls for design mix even though nominal mix is permitted, and share quantity, pour date and delivery location for standard transit-mixer delivery.
Actual grade selection is subject to structural design and project specification.
M25 has a characteristic cube compressive strength of 25 MPa, in the standard-concrete category, where design mix is mandatory under IS 456:2000. It is commonly considered where a higher durability or load requirement than M20 applies. Two projects both specifying M25 can carry different water-cementitious ratio requirements depending on exposure condition — confirm exposure class alongside the strength grade when ordering, not the grade number alone.
Actual grade selection is subject to structural design and project specification.
M30 has a characteristic cube compressive strength of 30 MPa. It is commonly considered for structural RCC, commercial construction, slabs, beams, columns, foundations and infrastructure work. If the pour requires pump placement, raise it early — pumping affects the workability the mix design needs to deliver, and it is easier to confirm before batching than after the mixer arrives.
Actual grade selection is subject to structural design and project specification.
M35 has a characteristic cube compressive strength of 35 MPa. It is commonly considered for higher-strength structural applications in commercial and infrastructure work, including columns and industrial floors carrying heavier loads than M25–M30 members. At this grade, confirm the specific durability or load data your engineer has specified rather than assuming a standard specification applies uniformly.
Actual grade selection is subject to structural design and project specification.
M40 has a characteristic cube compressive strength of 40 MPa. It is commonly considered for high-demand structural applications across infrastructure, commercial and industrial work. A higher grade number is not itself a marketing claim — suitability is determined by the structural requirement, not by picking the highest available number. Larger or continuous pours at this grade benefit from confirming discharge sequencing and site access ahead of delivery.
Actual grade selection is subject to structural design and project specification.
M45 has a characteristic cube compressive strength of 45 MPa, toward the upper end of the standard-concrete range rather than the high-strength category, which begins at M60. It is commonly considered for demanding commercial or industrial structures and special RCC work. Specification at this grade tends to be more rigorous — confirm target mean strength and sampling/testing frequency directly with your requirement rather than assuming a lighter-grade procurement process applies.
Actual grade selection is subject to structural design and project specification.
M60 denotes a characteristic cube compressive strength of 60 MPa at 28 days, the entry point into the high-strength concrete category. Above M55, IS 456's standard design tables may not directly apply — higher-strength concrete requires experimental data and performance-based mix evaluation specific to the project rather than the standard tables used for ordinary and standard grades. M60 is commonly considered for specialised high-strength and precast applications, and is supplied on request rather than as a routine stock grade.
This is a materially different procurement conversation than ordering M20–M45 — discuss your requirement directly rather than assuming standard-grade procurement timelines or documentation apply.
The correct RMC grade is determined by the structural design and project specification, not simply by choosing the highest available grade. Structural engineers set the requirement based on design loads, exposure conditions, durability needs, member type and construction method. This page provides technical reference information; it does not substitute for structural design.
Questions worth putting to your engineer if the requirement is still being assessed:
Share the application and project details with your enquiry and OM Group can discuss the requirement and quantities with you.
Required workability should be specified according to placement method and project requirement — no universal slump figure is published here, and none is invented.
Pumpability depends on aggregate grading, workability, mix design, admixtures and pumping distance. Not every mix is automatically pumpable — discuss the requirement directly.
Durability depends on mix design, water-cementitious ratio, materials, curing, exposure, cover, placement and workmanship. A higher M-grade number does not automatically mean more durable.
Typical RMC practice includes raw-material checks, batching accuracy, fresh-concrete checks, sampling, cube testing and delivery documentation — stated as typical industry practice, not a specific certified process unless separately confirmed.
Characteristic strength is the value below which no more than 5% of test results are expected to fall — a single cube result should never be read in isolation against the grade number.
RMC quality does not end at delivery. Final performance depends on placement, compaction, finishing and curing — all outside IS 4926's production-and-supply scope and outside OM Group's delivery responsibility.
Site access, pour schedule, pump arrangement and discharge planning affect scheduling — no universal delivery time is promised. Prepare access, manpower, pump (if required), pour area and discharge location ahead of the scheduled delivery.
RMC is commercially supplied and invoiced by volume of fresh compacted concrete, in cubic metres (m³). Wastage allowance and pour sequencing should be discussed at ordering — no fixed truck capacity is published unless separately confirmed.
Price depends on grade, quantity, mix specification, delivery distance, pumping requirement and current material costs. No "starting from ₹X" figure is published without a genuine current rate — OM Group quotes against the specific requirement.
Foundation and footing pours, subject to the structural design's grade requirement.
Standard structural elements across residential and commercial construction.
Villa, plot and residential RCC work, typically at ordinary or standard grades.
Commercial towers and industrial structures, subject to project specification.
Infrastructure work and larger continuous pours, coordinated to the pour schedule.
Retaining structures and raft foundations, subject to structural design.
Every application above is subject to structural design and project specification — this page is a technical reference, not a design substitute.
RMC is produced at batching plants at Kundaim and Thivim, operated by Sabsol Qualitech Industries LLP under the OM Group brand — not resold from a third party.
M20 through M45 supplied as standard, with high-strength grades such as M60 available on request against project confirmation.
Delivery across North and South Goa on an owned transit-mixer fleet, coordinated with the same operation that dispatches OM Group's aggregate and sand.

Definition
Ready Mix Concrete (RMC) is concrete produced under controlled batching and mixing conditions and supplied to a construction site in a fresh state for placement, rather than mixed on site.
RMC is the commonly used abbreviation for Ready Mix Concrete.
Raw materials are stored and proportioned at a batching plant to a specified mix design, mixed under quality control, then transported by transit mixer for site delivery and discharge.
RMC is batched under controlled plant conditions with batch-to-batch consistency managed at production; site-mixed concrete is prepared on site, with consistency depending on site practice and crew.
M20 designates a concrete grade with a characteristic cube compressive strength of 20 MPa at 28 days.
Grades
M25 designates a concrete grade with a characteristic cube compressive strength of 25 MPa at 28 days, classified as standard concrete requiring design mix.
M30 designates a concrete grade with a characteristic cube compressive strength of 30 MPa at 28 days.
M40 designates a concrete grade with a characteristic cube compressive strength of 40 MPa at 28 days, commonly considered for high-demand structural and infrastructure work.
M45 is a concrete grade with a characteristic cube compressive strength of 45 MPa, toward the upper end of the standard-concrete range under IS 456:2000, not classified as high-strength.
High-strength concrete under IS 456:2000 begins at M60. M25 through M55 are classified as standard concrete, not high-strength, even though design mix is mandatory across that range.
M60 is a high-strength concrete grade with a characteristic cube compressive strength of 60 MPa, requiring performance-based mix evaluation rather than IS 456's standard design tables. OM Group supplies M60 on request.
M20 through M45 are supplied as standard. High-strength grades such as M60 are available on request, subject to project-specific confirmation. Share your requirement for current availability.
Technical
Characteristic compressive strength is the strength below which no more than 5% of test results are expected to fall — the statistical basis for the grade designation.
Cube strength is the compressive strength measured from a standard 150mm cube specimen, typically tested at 28 days.
Target mean strength is the mean strength a mix design aims for, set above the characteristic strength to statistically ensure the characteristic value is met across a batch of results.
IS 4926:2003 is the Indian Standard governing the production and supply of Ready Mixed Concrete — batching, mixing, quality control and delivery documentation.
IS 10262:2019 is the Indian Standard guideline for concrete mix proportioning, used to design the mix for a specified grade.
IS 456:2000 is the Indian Standard code of practice for plain and reinforced concrete, and is the source of the concrete grade table used to classify ordinary, standard and high-strength concrete.
Nominal mix uses fixed proportions permitted only at M20 and below under IS 456:2000. Design mix is proportioned specifically to the project's materials and requirement, and is mandatory from M25 upward.
Mix Design
Concrete mix design is the process of proportioning cement, aggregates, water and admixtures to meet a project's strength, workability and durability requirements, referenced against IS 10262:2019.
Water-cement ratio is the ratio of water to cementitious material in a mix, a primary driver of both strength and durability.
Characteristic strength, target mean strength, water-cementitious ratio, workability, aggregate grading, cementitious content, admixture use, durability requirement and exposure condition all feed into the mix design.
No — mix proportions are project-specific and determined through the mix design process, not published as a generic recipe.
Quality
Typical RMC practice includes raw-material checks, batching accuracy control, fresh-concrete checks such as slump, sampling, cube testing and delivery documentation.
Primarily through cube compressive-strength testing at specified ages, alongside fresh-concrete checks like slump at the point of delivery.
A cube test measures the compressive strength of a standard 150mm concrete cube specimen, typically at 28 days, used to verify the mix meets its characteristic strength.
Characteristic strength is a statistical value — up to 5% of results are expected to fall below it by design. A single result needs to be read against the full batch of test results, not treated as a pass/fail on its own.
A delivery ticket is provided with each dispatch, with further documentation available on request, subject to what applies to the specific order.
Applications
Yes, subject to the structural design's grade requirement for the specific foundation.
Yes, across the standard grade range, subject to structural design.
Yes. Residential RCC commonly uses M20 or M25, subject to the project's structural design.
Yes, across the M20–M45 standard range and M60 on request, subject to project specification.
Commonly M20 to M30 depending on the structural design — this is not a prescription, and the actual requirement should come from your engineer.
Pumping
Pumpable concrete is a mix with workability and grading suited to placement via concrete pump, depending on aggregate grading, admixtures and pumping distance.
No. Pumpability depends on the specific mix design and placement conditions — confirm the pump requirement before ordering so it can be reflected in the mix.
Pump distance, placement conditions and required workability — share these with your enquiry so the mix design can account for pumping.
