摘要

Dry spraying-material, useful as pre-prod. of a building front or wall rough plaster, contains, by wt. 53-56 (56) % white cement, 3.5-6 (3.5)% white Ca(OH)2, 18-20 (18.5) % perlite, 3-4 (3.5)% ground Styropor (RTM) scrap, grain-size 1-2mm, 2.5-3.5 (3)% prefoamed Styropor (RTM), grain-size 0.2-0.3 mm, 13.5-15 (14.9)% Al silicate Al2SiO5 and 0.5-0.6 (0.6)% Me cellulose. Compsn. is used as a rough plater miscible with water on building site to form a stiff slurry. Slurry has improved workability, good heat-insulation and is light, e.g. 50- 1 dry prod. weigh only 10 kg.
