Mortar & cement calculator

Reference market rates

Estimate mortar volume and materials (cement, sand, lime) for masonry by wall thickness, mortar type and grade — common reference mix ratios.

Inputs

Enter wall area and choose thickness, mortar type and grade.

m²
Result

Enter an area and press “Calculate materials” to see the result.

Source & verification
Reference market rates

The coefficients/rates come from commonly used market references in Vietnam — not TCVN, not the applicable norms for your project. Use as a starting point and adjust to your case.

Mortar mix proportions by mortar grade — reference consumption rates commonly used in Vietnam, not TCVN. Adjust to your actual mix ratio.

About the mortar & cement calculator

Quickly estimate mortar, cement, sand (and lime for lime-cement-sand mortar) for a masonry wall — a reference answer to “how many cement bags to build a wall”.

What you enter

Wall area (m²), wall thickness (110/220/330), mortar type (lime-cement-sand or cement-sand) and mortar grade (25/50/75/100).

What the result means

Mortar volume (m³), cement (kg and ≈ 50 kg bags), sand (m³) and lump lime (kg for lime-cement-sand mortar) — per reference mortar-per-m³ rates by thickness.

Use cases

Rough material estimates for masonry in early cost plans, quick bag counts for one room/floor, cross-checking quantities in contractor quotes.

Mortar-per-m³ and grade mix ratios are common reference values (often cited from material norm 1776/BXD-VP and construction textbooks). Actual mix depends on cement type, sand moisture, lime/admixtures and required strength — check the norms applied to your project before ordering.

Worked example

A 220 wall of 40 m² → masonry ≈ 8.8 m³; mortar ≈ 0.24 m³/m³ → ≈ 2.1 m³; lime-cement-sand M75 needs ≈ 450 kg cement (≈ 9 bags), ≈ 95 kg lime and ≈ 2.2 m³ sand.

Frequently asked questions

Lime-cement-sand vs cement-sand mortar?

Lime-cement-sand (tam hợp) adds lump lime so it is more workable and uses less cement at the same grade; cement-sand (no lime) needs more cement but is simpler to stock — the tool has mix ratios for both.

How much mortar per m³ of wall?

Reference ≈ 0.23 m³ for 110 walls, ≈ 0.24 for 220 and ≈ 0.25 for 330+ (solid bricks) — the brick/mortar ratio changes with brick size.

Which mortar grade should I pick?

M50–M75 is common for residential walls; lower grades for light partitions, higher for load-bearing or damp locations — follow the design specification.

How is cement converted to bags?

The tool uses the common 50 kg bag in Vietnam (rounded up); check the actual bag size of your cement brand when ordering.

How it works

The tool computes masonry mortar and its materials: masonry volume = area × thickness; mortar volume = masonry volume × mortar per m³ (reference ≈0.23–0.25 m³/m³ by thickness); materials = mortar volume × grade-based mix proportions.

Common Vietnamese reference mixes (often cited from material norm 1776/BXD-VP and construction textbooks): lime-cement-sand mortar M50 ≈ 164 kg cement + 57 kg lump lime + 1.07 m³ sand per 1 m³ of mortar; higher grades need more cement and less lime. Cement is converted to 50 kg bags.
