| 摘要 | PURPOSE:To obtain the title compsn. having high compressive strength and high precision of levelling and permitting execution of a floor surface having a large thickness for the adjustment of its unevenness in a short time without requiring skillful plastering technique by mixing an aggregate having a specified grain size distribution and specified specific gravity with a levelling material. CONSTITUTION:A compsn. is obtd. by mixing 0.1-2 pts.wt. fluidizing agent, 0.05-2 pts.wt. viscosity adjusting agent (e.g., CMC, PVA,), if necessary, 0.1-4 pts.wt. setting accelerator (e.g., CaCl2) and 0.05-0.3 pts.wt. antifoaming agent, etc., with 100 pts.wt. self-levelling agent comprising a gypsum or an inorganic cement compd. Then, 200-500 pts.wt. aggregate (e.g., sand, crushed stone, granulated blast furnace slag) having | ||||||
