Coarse Aggregate Absorption %

Fine Aggregate Fineness Modulus FM

Cement Specific Gravity SG

Water Temperature °C

Admixture Dosage mL/100kg

📏 Fine Aggregate Gradation

Enter sieve analysis for sand. Use ASTM C33 limits for concrete sand.

📏 Coarse Aggregate Gradation

Enter sieve analysis for stone. Use ASTM C33 size #57 or #67 limits.

🌡️ Environmental Exposure

Select exposure class per ACI 318: F0-F3 (freeze-thaw), S0-S3 (sulfate), C0-C2 (corrosion), W0-W1 (water contact).

🧪 Trial Batch Verification

Always verify with trial batches per ACI 211. Adjust water for slump, air, and strength.
