摘要:
The present invention provides a two component geopolymer composition of wherein one component comprises a dry mix of an aluminosilicate, such as flyash, geopolymer precursor and one or more epoxy multilayer polymer particle redispersible polymer powder (RDP) having an epoxy resin core and an alkali soluble polymer shell, the epoxy resin having a calculated glass transition temperature (Tg) of from 7 to 45 °C, and, wherein the other component, comprises one or more alkaline silicate geopolymer precursor, preferably in the form of an aqueous solution. The two-component compositions having from 1 to 20 wt.% of the RDP, based on solids, and provide greater formulation flexibility to make geopolymer compositions having improved tensile strength.
