摘要:
Disclosed are a hydraulic binder composition containing at least 50% by weight of ground granulated blast furnace slag and a system for activating the slag, the system containing at least calcium sulphate, at least one product chosen from a source of Portland clinker and lime, at least one aluminium derivative and at least one alkali metal or alkaline earth metal salt; containing a ready-to-mix building material composition comprising such a hydraulic binder and aggregates of inert material capable of being agglomerated in the presence of an aqueous phase; and a process for employing the ready-to-mix composition containing a stage of mixing the said composition with water for the purpose of the preparation of a building material, such as a concrete or mortar, and in particular an adhesive mortar, pointing mortar or levelling mortar or coating.
摘要:
The invention relates to a liquid bi-component composition comprising a silylated polymer having alkoxysilane functions, an epoxy resin, an amine catalyst for the epoxy and a catalyst for silanol condensation, and an adhesion promoter or a coupling agent. After crosslinking, the liquid composition according to the invention makes it possible to obtain a waterproofing membrane suitable for pedestrian and/or vehicle traffic.
