Abstract

The invention relates to a thermal- insulating concrete hollow building-block, comprising cement, stone fragment powder, polystyrene particle, adhesion promoter and water. The weight proportions of said raw material are follows: cement: stone fragment powder: polystyrene particle: adhesion promoter: water= 1: 6- 9: 0.005- 0.05: 0.01- 0.02: 0.35- 0.5. The raw material is stirred, shaped, stewed for one hour, and produced to hollow building-block. The proper amount of polystyrene particle in the block makes the thermal conductivity coefficient of block concrete be reduced to 0.5 (W / m. K), the thermal conductivity coefficient of block-work partition be reduced to 1.8 W / (m2. K), the average thermal resistance of wall be reduced to 0.30 m2.K / W, and the thermal inert index be maintained at about 6.0.

Description

technical field [0001] The invention relates to a thermal insulation concrete hollow block and a preparation method thereof. Background technique [0002] Domestically, four technical approaches have been taken to improve the thermal performance of small concrete hollow blocks, namely, using lightweight aggregate concrete, changing the block hole structure, filling the block cavity with thermal insulation materials, and adopting a composite structure. The report of changing the pore structure of the block is not narrated because it has nothing to do with this patent. [0003] Reports on the use of lightweight aggregate concrete include: Fu Xiangtao [1] ZMQ Tang Xudong [2]'s QTC lightweight composite block uses expanded perlite as aggregate, Wang Jinchang et al. [3] successfully developed ultra-light ceramsite concrete composite thermal insulation block , Liu Guoqiang [4] used microporous lightweight concrete as the base material, and Zhu Weizhong [5] studied the thermal per...
