<p>PROBLEM TO BE SOLVED: To obtain a lightweight and an incombustible heat-insulating layer on a surface of architecture and civil architecture. SOLUTION: The layer includes hydraulic cement, an inorganic lightweight aggregate having bulk specific gravity of 0.05 to 0.15 and mean grain size of 50 to 1,000μm, a viscosity modifier having the ratio of methyl cellulose and ethyl hydroxy ethyl cellulose is from 20 to 80 to 80 to 20, pulp and synthetic resin emulsion. Though it is hydrolyzed and mixed, lightweight aggregate is hard to be crushed, even though it is fed by pressure of a pump, the specific gravity remains almost same as a mixing product when it was manufactured and thicker application can be made by spraying Further, the formed heat- insulating layer has incombustibility.</p> |
