Abstract

The invention discloses fiber composite concrete with high fire resistance. The fiber composite concrete comprises, by weight, silicate cement, natural oil stone, gelatin fibers, fatty acyl citrate, modified polycaprolactone fibers, sodium methyl silanol, poly-oxyalkylene alkyl ether sulfate, acrylic acid-acrylate copolymers, sodium tripolyphosphate, 5-6 parts of citric acid-chitosan, ethylene distearic amide, calcium carbonate whiskers, ethylene vinyl acetate, vinyl polysiloxane, silicon dioxide micro-powder, methacrylic acid, hexadecyl trimethyl ammonium bromide, ammonium persulfate, manganese carbide, quartz glass powder and nanometer titanium oxide water repellents. The fiber composite concrete has the advantages that the adding ranges of various components are determined, polycaprolactone fibers are modified, the different components are pretreated, accordingly, the obtained fire-resistant fiber composite concrete is high in strength and good in fire resistance and mechanical property and can be uniformly dispersed, and the concrete workability of fibers can be improved.

Description

technical field [0001] The invention belongs to the technical field of concrete preparation, and in particular relates to a fiber composite concrete with high fire resistance and a preparation method thereof. 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 dir...
