A very high strength SCC (self compacting concrete). It differs from Dump Mixes in that it can be carried in buckets, but direct discharge into moulds or shuttering is preferred. Kerabrade A is self leveling and self de-airing and requires no vibration. It is derived from Perimeter 1 which was developed for quick setting ultra thin perimeter walls; It develops 136 MPa in 4 days. Not for use at high temperatures. It is volume stable. Wear; It should wear to a smooth surface, because the matrix is as hard as the aggregate. (Most abrasion resistant materials become rough as the aggregate protrudes.) Kerabrade A is therefore ideal for ore chutes and sliding applications.
Maximum particle size is 7mm.

78 weight parts powder to 22 weight parts liquid binder.
100:28 or +28% liquid binder.
