Concrete Mix Design
Calculator

Excel-based tool that automatically computes concrete ingredient quantities based on desired strength

🧱📊

I have developed an Excel-based mix design calculator that automatically computes the required quantities of concrete ingredients based on the desired strength. It follows the principles of IS10262:2019 and IS456:2000 and provides quick, accurate, and user-friendly results.

TYPE 01

Nominal Mix

Nominal mixes are pre-determined proportion ratios of cement, sand, and aggregates used for concrete grades up to M20.

Grade	Cement	Sand	Aggregate
M10	1	3	6
M15	1	2	4
M20	1	1.5	3

✅ Suitable for: Small projects, low-rise buildings, footpaths

🔬

TYPE 02

Design Mix

Design mix is the scientific method of proportioning concrete ingredients based on laboratory testing for grades above M20.

f'ck = fck + 1.65 × S
Water-Cement Ratio = Target Strength / (Cement × 0.5)

✅ Suitable for: High-rise buildings, bridges, dams, infrastructure
