What Is Concrete Mix Design?
A concrete mix design tells you, specifically, the exact proportions of cement, fine aggregate, coarse aggregate, and water needed to achieve your target strength grade on site.
This service is, therefore, not about testing hardened concrete — it is the upstream engineering step that determines whether your concrete will reach M30, M40, or M50 in the first place.
Consequently, getting the proportions wrong wastes cement, inflates costs, and risks structural failure during inspection.
| Type | Grades |
|---|---|
| PCC (Plain Cement Concrete) | M10 M15 |
| RCC (Reinforced Cement Concrete) | M20 M25 M30 M35 M40 M45 M50 M55 M60 |
Applicable Standards — IS 10262:2019
Jancy Labs conducts this service strictly as per IS 10262:2019 — Concrete Mix Proportioning: Guidelines.
IS 10262:2019 — Mix Proportioning Guidelines
Sets out the complete methodology for proportioning concrete mixes based on target mean strength, standard deviation, and material properties. Furthermore, all component material tests follow their respective IS standards.
Supporting Material Standards
Additionally, the individual tests supporting your mix design follow: IS 383:2016 — Coarse and Fine Aggregate Specification, and IS 12269:2013 / IS 8112:2013 — Ordinary Portland Cement Specification. Our scope is verifiable on the NABL India portal → under TC-12176.
Why This Service Matters for Your Project
A properly documented concrete mix design, moreover, protects your project at every approval stage. Specifically, here is what it delivers:
- Structural compliance: CPWD, TNPWD, and CMDA require an IS 10262:2019-compliant mix design for all RCC work — therefore, no mix design means no structural approval.
- Cost control: A properly proportioned mix prevents over-cementation; consequently, even a 5% cement reduction on a large pour saves significant material cost without compromising strength.
- Site rejection avoidance: Contractors using nominal mixes on engineered structures risk third-party audit rejection; however, a documented design mix provides defensible, traceable evidence.
- Grade-specific optimisation: High-strength grades like M50 and M60 need precisely controlled w/c ratios — as a result, only a designed mix can reliably and consistently hit these targets.
- TANGEDCO and MES projects: Infrastructure projects under TANGEDCO, MES, and BRO increasingly mandate design mix documentation — notably, this applies to all structural concrete elements.
⚠️ Skipping a proper mix design on a government-funded structural project is, therefore, not a cost saving — it is, in fact, a compliance risk that can halt your entire project mid-execution. View all Design Mix Testing services →

How to Get Your Concrete Mix Design Done
Send Your Samples and Project Details
To prepare your mix design as per IS 10262:2019, Jancy Labs requires the material samples and project information listed below.
We Test and Design
We first perform NABL-accredited component tests on the submitted aggregates and cement, then calculate mix proportions following IS 10262:2019, prepare trial mixes, and cast cubes for 7-day and 28-day verification.
You Receive Your Certified Report
Your concrete mix design report contains full material properties, mix proportions, and trial mix results — delivered by email PDF within 24 hours of results being ready.
| Material | Approximate Quantity |
|---|---|
| Coarse Aggregate (20 mm) | 50–75 kg |
| Coarse Aggregate (12.5 mm or 10 mm, if applicable) | 25–40 kg |
| Fine Aggregate (river sand or M-sand) | 30–40 kg |
| Ordinary Portland Cement (53 Grade / 43 Grade) | 25–40 kg |
Exact quantities may vary based on number of design grades and trial mix batches.
How to Collect Samples
- Collect aggregate samples from the actual stockpile or quarry supply intended for your project
- Avoid collecting from segregated or weathered surface material
- Use the same cement brand and grade as planned for site use
How to Pack
- Pack aggregates in heavy-duty sealed polythene bags or jute bags
- Label each bag: Project Name | Site Location | Material Type | Grade/Size | Sample ID | Date
Project Details to Share
- Required concrete grade(s) and type (PCC / RCC)
- Exposure condition (mild / moderate / severe / very severe)
- Maximum nominal aggregate size

Our Concrete Mix Design Process — as per IS 10262:2019
Material Testing & Target Strength
- First, collect and register the client's aggregate and cement samples along with project details and exposure condition.
- Next, conduct NABL-accredited sieve analysis and specific gravity tests on coarse and fine aggregates as per IS 383:2016.
- Then, perform NABL-accredited cement testing — specifically fineness, consistency, setting time, and compressive strength — as per the IS 4031 series.
- Subsequently, determine target mean strength based on the design grade, standard deviation, and risk factor as per IS 10262:2019 Clause 3.
Finalising the Concrete Mix Proportions
- Consequently, calculate the water-cement ratio, water content, and cement content using IS 10262:2019 design tables and the verified material test data.
- Next, proportion fine and coarse aggregates by volume or mass to achieve the target workability and specified grading requirements.
- Then, prepare trial mixes, check workability by slump test, and cast concrete cubes — specifically 3 cubes for 7-day and 3 cubes for 28-day testing.
- Finally, test cubes at 7 days and 28 days; subsequently verify results against the target mean strength and IS 456:2000 acceptance criteria.
