摘要

Flowable material, as dry compsn. ready to mix with water, for use as rough casts for high and low building pts. e.g. frontages of masonry or partition walls, ceilings and prefabricated concrete pts., consists, by vol. of 10-40% cement, 10-90% synthetic resin dispersion, e.g. polyvinyl acetate, acrylic or epoxy resin dispersion or emulsion, 2-10% Al2SiO5, 10-50% SiO2, pref. 5% hard foam, e.g. prefoamed polystyrene granules or beads and 5% 3-15 mm long silicate glass fibres. Pref. compsn. contains, by wt. 30 pts. cement, 8 pts. resin dispersion, 8 pts. Al2SiO5, 44 pts. SiO2, 2.4 pts. fine hard foam beads, 0.6 pts. coarse hard foam beads and 1 pt. silicate glass fibres.
