Abstract: An inorganic binder having calcium silicate sites which are connected the one with the other by alumina-silica phosphate bonds, whereby at least a portion of said alumina-silica bonds are alumina-silica phosphate bonds having a weight ratio Al2O3/SiO2 ranging from 0.3:1 to 10:1, a weight ratio Al2O3/P2O5 ranging from 0.0005 to 0.04, and a weight ratio P/B ranging from 20:1 to 100:1, whereby the inorganic binder further includes a waterproof and/or water repellent silicon compound or mixture.
Abstract: A binder, a composition, a product and a kit, as well as a process for preparing the binder and composition, are directed to a composition useful as an inorganic phosphate binder, which binder is characterized as having calcium silicate sites which are connected the one with the other by alumina-silica phosphate bonds, and a filer.
