PARTICLE COATED BONDING SYSTEMS FOR HYDRATABLE CEMENTITIOUS COMPOSITION CASTING AND METHODS FOR MAKING SAME

摘要

Coated articles, methods for making such articles, and waterproofing systems incorporating these. An exemplary coated article comprises a body wi th surface coating of inorganic particles reactive with hydroxide generated fro m hydration of concrete or mortar to form hydration products. The articles are designed to be used with cast concrete or masonry. The inorganic particles comprise at least one of (a) aluminum oxide trihydrate; (b) silica dioxide; (c) fly ash; (d) blast furnace slag, (e) silica fume; (f) an alkali or alkaline eart h metal salts; or mixture thereof. The particles improve bonding with hydratable cementitious compositions that are cast against the coated surface and allow ed to set.
