Rockbond Admix 711 Product Information Sheet

Description

ROCKBOND ADMIX 711 (RB A711) powder is blend of waterproofing admixtures which has been specially designed for use with Portland cement mortars and non flow concretes. The admixture, when mixed with cementitious materials release compounds which react with the alkalis present in the cement. As the mortar or concrete hardens, insoluble crystals are formed in the pores and capillaries of the cement which reduce the passage of water and aggressive chemicals through the material. The powder is ready to use, supplied in quantities to order, packaged in moisture proof durable bags and has a shelf life of 5 years.
