CONCRETE FIREPROOF COATING COMPOSITION AND CONCRETE FIREPROOF COATING MATERIAL MADE THEREOF

摘要

Provided are a fireproof coating material composition for concrete which is applied on the surface of high performance concrete to prevent the spalling of concrete in case of a fire, a fireproof coating material for concrete constructed by using the composition, a panel for fireproof coating using the composition, and a fireproof adhesive containing the composition. The fireproof coating material composition comprises 20-40 wt% of an aluminosilicate-based binder; 15-35 wt% of an alkali silicate-based curing agent; 20-40 wt% of a fireproof heat insulating aggregate; and 0-5 wt% of a functional additive. Preferably the aluminosilicate-based binder is at least one selected from a shaft furnace slag powder, fly ash, metakaolin, fumed silica, kaolin-based mineral, calcium silicate, and calcium aluminate; and the functional additive is at least one selected from a frothing agent, a dispersant, a thickener, an organic fiber, and an inorganic fiber.
