Filling narrow block cores and reinforced cells.
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 Fine grout is used
A high-slump cement-sand grout (no coarse aggregate) for pouring into narrow grout spaces and small block cavities. Placed wet enough to flow around reinforcing bar.
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.
