Description

ROCKBOND REPAIR CONCRETE (RB RC) powder is a specially formulated, pre-mixed, ready to use, cementitious concrete powder. The compound contains a blend of fine cements, high quality graded sands, crushed rock aggregates and a set of compatible admixtures. The material readily mixes with water to produce a flowing repair concrete which is self compacting and hardens to give a strong bonding, high strength product. The powder is packaged in 25kg moisture proof, durable bags and has a shelf life of two years.

Special Properties
