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.
Designed to the Department of Transport Specification for Highway Works.
Quickly and easily mixed with water, poured, pumped and placed.
Flowing consistency promotes penetration into confined spaces, and into weak and damaged concrete substrates.
The concrete will not segregate or bleed at the recommended water content.
Shrinkage compensated, with low alkali cements, equivalent Na2O below 3kg/m³.
Excellent bond strength, and good mechanical strengths.
Resistant to static, dynamic, cyclic and vibrational stresses.
Incorporates unreactive sands and aggregates safe from Alkali Silica Reaction (ASR).
High yielding, economical, non flammable, non toxic, odour free, user friendly and safe to use.
For general purpose and high performance concreting applications.
