🎯 Our Mission & Story
MixDesignCalc was founded in 2022 by a group of structural and concrete engineers frustrated by the gap between what IS 10262:2019 mandates and what most “concrete calculators” actually deliver. Too many tools produce numbers without showing their work, without referencing the standard clauses they claim to implement, and without any honest statement of their limitations. We built something different.
Our mission is simple: make rigorous, standards-based concrete mix design accessible to every engineer in India and beyond — whether they are a principal structural engineer at a major infrastructure firm or a fresh graduate working their first RMC plant posting. Every calculation we publish is traceable to a specific IS, ASTM, or EN clause. Every limitation we know about is documented. Every update to our data is logged with the date and standard reference that prompted it.

Our Founding Principle
“A concrete calculator that does not show which clause it is implementing is not a concrete calculator — it is a black box dressed up as one. Every number we produce must be traceable. Every limitation we have must be disclosed. The engineer using this tool carries professional responsibility for the structures built with its outputs — we owe them complete transparency about how our calculations work and where they stop being valid.”
— Dr. Ananya Krishnan, Co-founder & Lead Concrete Technologist
👩💼 Core Technical Team
Our core team combines deep concrete technology expertise with real-world site and laboratory experience. Every team member has hands-on experience with IS 10262 mix design, trial mix programmes, and structural concrete quality control — not just theoretical knowledge.

💎 Our Values — What We Stand For
📖
Standards Fidelity Above All
Every number we output is traceable to a specific IS, ASTM, or EN clause. We never use undisclosed algorithms or proprietary black-box calculations. If we can’t show our working, we don’t publish the number. Engineers must be able to verify every output independently.
🔍
Radical Transparency
Our methodology is fully documented — including every assumption we make and every limitation we know about. When our calculations are less accurate (such as slump prediction), we say so explicitly and quantify the expected deviation. We will never oversell what a calculation tool can do.
🛡️
Structural Safety First
When IS 456 and economic pressure point in opposite directions, IS 456 wins — always. We built the IS 456 compliance checker to make it impossible to inadvertently under-specify concrete for an exposure class. Structural safety is not a feature; it is the non-negotiable foundation of everything we build.
🌿
Sustainable by Design
We actively promote SCM substitution, optimised grade selection, and life-cycle cost thinking because they simultaneously reduce cost and carbon. Every reference page includes sustainability data alongside strength and cost data. The optimal concrete in 2026 is lower-carbon — and usually also cheaper over its service life.
🎓
Engineering Education
We are committed to making rigorous concrete technology accessible to every engineer — from IIT professors to first-year graduate engineers on their first RMC posting. Every formula we show, every limitation we document, every clause we reference is an educational moment for the next generation of concrete technologists.
🤝
Community-Driven Accuracy
When a user finds a discrepancy between our output and a standard, we review it within 24 hours, correct it if confirmed, and credit the reporter in our update log. Our accuracy improves because thousands of engineers scrutinise our calculations every day. We actively want to be corrected when we’re wrong.
🤝 Academic & Industry Partners
MixDesignCalc collaborates with leading academic institutions, standards bodies, and industry organisations to maintain accuracy, stay current with standards revisions, and contribute to the development of the concrete technology community in India and beyond.
