ABSTRACT:
A waterglass-based material containing an inorganic component A of an alkali metal silicate having a low viscosity and a high silica content and a component B having at least one fast hardening agent, preferably carbonic esters, and a hardening retarder of at least one further hardening agent which acts more slowly, preferably dialkyl carboxylates, in particular dimethyl succinate, dimethyl glutarate and/or dimethyl adipate. The material may also contain optional further additives, such as liquefiers, thixotropic agents, lubricants and fillers and the like. Processes for hardening a waterglass-based material and use of such a material for sealing pipelines, sewers and containers, for soil stabilization, coating and impregnation of materials and for the production of shaped articles are also indicated.
