Mix Quantities — M15 (1:2:4) Paths & Floors
Cement bags, sand and aggregate for M15 (1:2:4) Paths & Floors from wet volume with yield factor.
The 1:2:4 mix is folk engineering at its most durable — a century of garage floors and garden paths. Around M15 nominal mixes start being used structurally in modest work, which is precisely where the IS 456 cutoff (design mixes above M20) draws its line.
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 — M15 (1:2:4) Paths & Floors
Mix Quantities — M15 (1:2:4) Paths & Floors computes the governing relationship dry vol = wet × factor; split 1:2:4; cement at 1,440 kg/m³; water = w/c × cement live as you type. The 1:2:4 mix is folk engineering at its most durable — a century of garage floors and garden paths. Around M15 nominal mixes start being used structurally in modest work, which is precisely where the IS 456 cutoff (design mixes above M20) draws its line. 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 — M15 (1:2:4) Paths & Floors
- 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 1:2:4; 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.

Frequently asked questions
What formula does the mix quantities — m15 (1:2:4) paths & floors use?+
It evaluates dry vol = wet × factor; split 1:2:4; 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?+
The 1:2:4 mix is folk engineering at its most durable — a century of garage floors and garden paths. 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 M15 (1:2:4) Paths & Floors from wet volume with yield factor. A free concrete curing, maturity & strength tool. Around M15 nominal mixes start being used structurally in modest work, which is precisely where the IS 456 cutoff (design mixes above M20) draws its line. 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.
