Concrete strength classes

M10 nominal concrete

Entry nominal structural-adjacent mix. Common for kerb haunching and light, non-critical bedding.

Mix ratio

1 : 3 : 6

Cement : Sand : Aggregate

Proportions & strength

Designation	M10
Ratio (by volume)	1 : 3 : 6
Cement	1 part
Sand	3 parts
Aggregate	6 parts
Typical compressive strength	1,450 psi · 10 MPa
Typical use	Levelling courses, path bedding, kerb backing.

Planning reference. Strengths are typical values for a well-made mix at 28 days, not a guaranteed design strength. Structural work must follow your local building code and a qualified engineer's mix design.

Where M10 is used

Entry nominal structural-adjacent mix. Common for kerb haunching and light, non-critical bedding.

Nominal mixes like this are proportioned by volume on site and suit general and domestic work. Anything structural — reinforced, load-bearing or engineered — should use a design mix proportioned by weight from tested materials.

Need quantities? The volume calculators give the cubic yards, cubic metres and bag counts for the pour this mix goes into.
