Description

6.01 A220 Expansion Agent (Block Fill & Grout Modifier) is a special blend of expansion additives and other admixture powders. The powder contains an expansion additive, a super-plasticiser and anti-bleed agents. A220 also contains a stability aid for high flow materials.

This admixture is used to minimize settlement and segregation of the mix, and to produce flowing materials that are dimensionally stable and effective at filling voids.

A220 has been formulated to produce expansion between placement and the initials set of the grout.
