WERKWIJZE VOOR HET BEREIDEN VAN EEN CEMENTSAMENSTELLING.

摘要

A cement composition consisting of the product of a mixture of spray-dried hydrated silicate powder, a silica polymer-forming agent and water. The resulting inorganic silica polymer cement is capable of withstanding sustained exposure to high temperatures without loss of desirable mechanical properties and has a high degree of adhesive as well as compressive strength together with rapid room temperature curing characteristics. A siliceous filler may be added. In addition, a fluoride or halide fixation agent may be added so that the resulting cement product may resist higher temperatures.
