PURPOSE: To improve the denseness of surface, strength and hardening property at a low temp., to form a smooth surface and to form a thickened rugged pattern by consisting essentially of cement, a fine aggregate, a lightweight aggregate, a lightweight powder and a synthetic resin emulsion. CONSTITUTION: A uniform slurry is obtained by. blending (A) 100 pts.wt. cement, (B) 20-30 pts.wt. fine aggregate having 0.1-0.5mm average particle diameter, (C) 10-20 pts.wt. lightweight aggregate having 0.02-0.2 bulk density and 150-1200μm average particle diameter, (D) 10-30 pts.wt. lightweight powder having 0.20-0.80 bulk density and 30-300μm average particle diameter, (E) 10-20 pts.wt. synthetic resin emulsion expressed in terms of solid utter and, at the time of using, blending (G) water so as to be 50-100 in (water/cement) ratio, where the (water/cement) ratio can be lowered by blending (F) 0.1-2 pts.wt. water reducing agent, and if necessary, blending (H) 0.1-1 pts.wt. thickener and (I) 3-10 pt.wt. fibrous filler having 0.1-5mm fiber length and mixing them using a cement mixer. |
