Mix Quantities — M25 Site-Batched (1:1:2)
Cement bags, sand and aggregate for M25 Site-Batched (1:1:2) from wet volume with yield factor.
Where plants don't reach, M25-ish work gets batched at 1:1:2 — cement-rich and forgiving of moderate site sloppiness. It is also the most expensive way to buy strength; the bag count this returns is usually the argument that finally hires the ready-mix truck.
Formula
Note: Planning estimate only — strength for structural decisions (formwork striking, post-tensioning, loading) must be verified by site-cured specimens or a calibrated maturity system per the project specification.

About Mix Quantities — M25 Site-Batched (1:1:2)
Mix Quantities — M25 Site-Batched (1:1:2) computes the governing relationship dry vol = wet × factor; split 1:1:2; cement at 1,440 kg/m³; water = w/c × cement live as you type. Where plants don't reach, M25-ish work gets batched at 1:1:2 — cement-rich and forgiving of moderate site sloppiness. It is also the most expensive way to buy strength; the bag count this returns is usually the argument that finally hires the ready-mix truck. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Mix Quantities — M25 Site-Batched (1:1:2)
- 1Enter your values — Wet (finished) volume, Dry volume factor, Water-cement ratio, Wastage (sensible defaults are pre-filled).
- 2Read the live results: Cement (50 kg bags), Sand, Coarse aggregate, Water.
- 3Check the "with your numbers" line to see dry vol = wet × factor; split 1:1:2; cement at 1,440 kg/m³; water = w/c × cement substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Mix Quantities — M25 Site-Batched (1:1:2)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula dry vol = wet × factor; split 1:1:2; cement at 1,440 kg/m³; water = w/c × cement with authoritative sources cited on the page (IS 456:2000 — Plain and reinforced concrete code of practice; IS 10262 — Concrete mix proportioning guidelines)
- ✓Where plants don't reach, M25-ish work gets batched at 1:1:2 — cement-rich and forgiving of moderate site sloppiness.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the mix quantities — m25 site-batched (1:1:2) use?+
It evaluates dry vol = wet × factor; split 1:1:2; cement at 1,440 kg/m³; water = w/c × cement, exactly as published. Sources: IS 456:2000 — Plain and reinforced concrete code of practice; IS 10262 — Concrete mix proportioning guidelines. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Where plants don't reach, M25-ish work gets batched at 1:1:2 — cement-rich and forgiving of moderate site sloppiness. Planning estimate only — strength for structural decisions (formwork striking, post-tensioning, loading) must be verified by site-cured specimens or a calibrated maturity system per the project specification.
When is this calculator the right tool for the job?+
Cement bags, sand and aggregate for M25 Site-Batched (1:1:2) from wet volume with yield factor. A free concrete curing, maturity & strength tool. It is also the most expensive way to buy strength; the bag count this returns is usually the argument that finally hires the ready-mix truck. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
