MORTAR COMPOSITE FOR SOIL PAVEMENT WITH WEED PREVENTION CHARACTERISTICS, CONSTRUCTION METHOD OF SOIL PAVEMENT AND CONSTRUCTION METHOD OF WEED PREVENTION USING THE MORTAR COMPOSITE

摘要

A mortar composition for paving soil is provided to improve repair, moisturization and durability which are disadvantage of paving soil by mixing polyacrylamide which is polymer of high absorption and composite polymer mixing powder acrylic resin. A mortar composition for paving soil comprises one or more materials 80.5~92 weight% selected from soil and siliceous pozzolan powder, cement binder 5~15 weight%, water 1~3 weight% and a composite polymer binding material 0.5~1.5 weight%. The composite polymer binding material contains polyacrylamide and powder acrylic resin. The cement binder includes portland cement 35~60 weight%, calcium alumina cement or calcium sulfoaluminate 15~25.5 weight% and gypsum 5~15 weight% and one or more materials selected from promoter, retarder, and antifoaming agent.
