ROCKBOND ADMIX 402 (RB A402) powder is a ready to use blend of water reducing and accelerating agents that has been specially designed for use with Portland cementitious materials. The admixture will produce grouts and flowing concretes that develop a rapid gain in early compressive strength at 20ºC. The powder will also accelerate cementitious materials at low temperatures, or during the winter months when the weather is cold. The compound is supplied to order, packaged in moisture proof, durable bags and has a shelf life of 2 years
