Masonry grout

Coarse masonry grout

Adds pea gravel for larger grout spaces (bond beams, wide cores). Still placed at a high slump so it consolidates fully around reinforcement.

Mix ratio

1 : 3 : 2

Cement : Sand : Pea gravel

Proportions & strength

Designation	Coarse grout
Ratio (by volume)	1 : 3 : 2
Cement	1 part
Sand	3 parts
Pea gravel	2 parts
Typical compressive strength	2,000 psi · 14 MPa
Typical use	Filling wider block cores and bond beams.

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 Coarse grout is used

Adds pea gravel for larger grout spaces (bond beams, wide cores). Still placed at a high slump so it consolidates fully around reinforcement.

Grout is placed at a high slump so it flows fully around reinforcement and fills the cavity without voids. It is not the same as mortar, and it is not the same as tile grout.

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