FAQ
About Civil Engineering.
Which mix ratios and codes are supported?
The suite ships with M7.5, M10, M15, and M20 concrete presets plus 1:3, 1:4, 1:5, 1:6 mortar. Dry-volume factors follow industry practice (1.54 concrete, 1.33 mortar). Rebar weight uses IS 1786 (w = d²/162.28).
How are brick and block counts calculated?
We use standard modular brick (190 × 90 × 90 mm) and CMU block (390 × 190 × 190 mm) with a 10 mm mortar joint, then divide wall area/volume by the nominal brick/block size and apply your waste %.
Are beam-deflection results a design check?
They are a first-pass serviceability check comparing δ against L/250 for a simply-supported beam. Real designs must follow the applicable structural code (ACI 318, IS 456, Eurocode 2, AISC).
Do I need internet for these tools?
No. Every calculation runs locally in your browser. Nothing is uploaded, cached, or logged.
