Abstract

The invention discloses refractory concrete. The refractory concrete comprises, by weight, 100-120 parts of granulated blast-furnace slag, 8-12 parts of potash water glass, 4-6 parts of sodium hydroxide, 80-100 parts of Portland cement, 30-70 parts of fly ash, 100-150 parts of river sand, 200-250 parts of stone, 2-5 parts of modified carbon fiber cloth, 8-15 parts of expanded perlite, 2-4 parts of silicone rubber powder, 10-15 parts of modified polyethylene glycol, 2-3 parts of epoxy resin emulsion, 1-2 parts of disodium methylene bisnaphthalenesulphonate, 0.5-1.5 parts of sodium lignin sulfonate and 65-75 parts of water. The refractory concrete is good in fire resistance and good in mechanical performance.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a refractory concrete. Background technique [0002] Concrete is the most widely used man-made material in the world, and it is also the most important building structure material. Its safety under high temperature has attracted more and more attention from all over the world. The high temperature resistance and fire resistance of traditional Portland cement concrete are not ideal. Under the high temperature of the fire, the properties of concrete materials change in various aspects, causing stress redistribution inside components and structures, thereby reducing the performance of structural components and endangering the safety of the overall structure. Under fire, as the temperature rises, the material composition in the concrete will change due to the high temperature reaction, which directly affects the mechanical and thermal properties of the concrete. Therefore, while i...
