Inflaming retarding high-temperature-resisting foam concrete and preparation method thereof
The invention discloses inflaming retarding high-temperature-resisting foam concrete and a preparation method thereof. The concrete is prepared by mixing a gel material, heat-resisting aggregates, a liquid-state composition, an admixture and a foaming agent, wherein the gel material is slag silicate cement and grade-I fly ash; the heat-resisting aggregates comprise vitrified micro-beads, crushed clay clinkers, nano clay and corundum sand; the liquid-state composition comprises a water reducing agent, water and acrylic resin; and the admixture comprises phosphate, an inorganic fire retardant, glass fibers and calcium carbonate crystal whiskers. The inflaming retarding high-temperature-resisting foam concrete prepared by the preparation method has the advantages of small density, relatively high strength, low heat conductivity coefficient, good heat insulation performance and the like; and the combustion performance is grade A, and the fireproof limit can reach 4 hours so that the inflaming retarding high-temperature-resisting foam concrete is a fireproof heat-insulation material with a good comprehensive performance.
