SILRES BS 1802

SILRES®BS 1802 is used in undiluted form as an admixture for the integral waterproofing of fresh concrete. Moreover SILRES®BS 1802 can be used as water resisting admixture for non-load bearing manufactured concreteproducts. It is certified for Mass hydrophobizing of concrete objects and cementitious construction elements according to EN 934/2. Properties In the fresh concrete, SILRES®BS 1802 reacts with the water in the mixture. The so formed active substance greatly reduces the concrete’s water absorbency after hardening, but without blocking any pores or capillaries. Building materials treated integrally with SILRES®BS 1802 retain very high water-vapor permeability. One of the main degradation mechanisms in concrete, the so called ASR (alkali-silica-reaction) is effectively inhibeted by an integral treatment with SILRES®BS 1802, extending the service life of the construction material significantly.
