A MANUFACTURING PROCESS OF PREPACKAGED REPAIRING MATERIALS USING RAPID SETTING AGENT COMPOSITE BY INORGANIC ALKALI AND CEMENTIOUS)

摘要

A rapid set repairing material using powdery resin is provide to pack in a form of a premix and to be excellent in low temperature hardening, chemical resistance, adhesion properties and weather resistance. The rapid set repairing material comprises 20 to 35 wt% of Portland cement, 3 to 7 wt% of a rapid set agent, 2 to 3 wt% of powdery resin for cement admixture including any one selected from ethylene vinyl acetate(EVA) or vinyl acetate/vinyl versatate(Va/VeoVa), and 60 to 70 wt% of silica. The rapid set agent includes 21 to 35 wt% of calcium aluminate cement(CAC), 21 to 25 wt% of calcium sulfur aluminate(CSA), 8 to 10 wt% of lithium carbonate(Li2CO3), 3 to 6 wt% of caustic lime, 20 to 25 wt% of anhydride gyps(CaSO4) and 8 to 13 wt% of aluminum hydroxide(Al2(OH)3).
