A COMPOSITION OF FINISHING MATERIAL FOR PROTECTION A SURFACE OF THE CONCRETE STRUCTURES USING LADLE SLAG TO GROW ON CRYSTAL BY THE HYDRATION

摘要

PURPOSE: A finishing material composition capable of using as a surface protector of a concrete structure is provided to protect the surface of concrete from various deterioration factors using the swelling property of bentonite. CONSTITUTION: A finishing material composition capable of using as a surface protector of a concrete structure, using a ladle slag crystal-growing reaction contains 10~30wt% of cement, 20~50wt% of silica or limestone powder, 20~50wt% of powder additive including ladle slag and granulated blast furnace slag in a ratio of 2~5:10~40; 1~3wt% of anhydrous gypsum, 2~7wt% of ethylene vinyl acetate polymer powder, 3~10wt% of bentonite powder, and 1~3wt% of sodium carbonate. The composition additionally contains 1~8wt% of inorganic pigment.
