Problems solved by technology

Building materials with cement as the main cementitious material usually cannot withstand high temperatures. This is because the hydration products based on ettringite decompose at 70 degrees, causing damage to the hardened slurry system and making the building materials Reduced strength

Abstract

The invention discloses a high temperature resistant water polystyrene material. A mineral composition of the high temperature resistant water polystyrene material comprises tricalcium silicate, dicalcium silicate, and amorphous silica powder, wherein the weight content of the tricalcium silicate is 25 to 50 percent, the weight content of the dicalcium silicate is 25 to 40 percent, the weight content of the amorphous silica powder is 25 to 50 percent, and a ratio of calcium to silicon is less than 2. The invention also discloses mortar made of the high temperature resistant water polystyrene material, which is obtained by uniformly mixing the following raw materials in parts by weight, comprising: 350 to 650 parts of high temperature resistant water polystyrene material, 200 to 500 parts of mortar, 50 to 200 parts of active mineral admixture, 100 to 200 parts of refractory filler, and 0.5 to 5 parts of dispersant. The mortar thus prepared has excellent high temperature resistance and can be used for construction in contact with high temperature building parts.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-temperature-resistant hydraulic adhesive material and mortar made from the high-temperature-resistant hydraulic adhesive material. Background technique [0002] At present, the main representative of hydraulic cementitious materials is Portland cement, and the main clinker minerals of cement are tricalcium silicate, dicalcium silicate, C 3 A,C 4 AF and gypsum, the hydration products of cement are mainly ettringite, hydrated calcium silicate gel. Building materials with cement as the main cementitious material usually cannot withstand high temperatures. This is because the hydration products based on ettringite decompose at 70 degrees, causing damage to the hardened slurry system and making the building materials Reduced strength. Therefore, the technology of high-temperature-resistant building materials based on high-temperature-resistant hydraulic adhesive materials s...
