Abstract

The invention relates to inorganic heat insulating mortar used by light-weight heat insulating brick masonry and a preparation method thereof, wherein, the inorganic heat insulating mortar has the raw material compositions and weight contents of 10-30 parts of fly ash, 15-35 parts of vitreous microballon, 1-8 parts of swell soil, 1-10 parts of lime, 250-400 parts of sand and 100 parts of cement. The preparation method comprises the following steps of: uniformly mixing the fly ash, the sand, the swell soil, the hydrated lime and the cement through a machine, adding the vitreous microballon, uniformly mixing through the machine once again and packing by fixed amount. The inorganic heat insulating mortar has the advantages of high strength, low thermal conductivity and good workability, which can avoid the problems of cracking and 'heat bridge' of the masonry body caused by the use of common masonry mortar when being matched with light-weight heat insulating bricks.

Description

technical field [0001] The invention relates to a building material, in particular to an inorganic heat-retaining mortar for building light-weight heat-retaining bricks and a preparation method thereof. Background technique [0002] With the innovation of national wall materials and the deepening of the promotion and application of energy-saving buildings, various types of lightweight insulation bricks have been widely used. The dry bulk density of building mortar is generally 1600-1800kg / m 3 , the thermal conductivity is 0.8-1.1W / m·K, and most of them are prepared on the construction site, which is greatly affected by the conditions of the construction site, and the mortar has different strength and unstable quality. The dry bulk density of lightweight insulation bricks is generally 400-900kg / m 3 , the thermal conductivity is 0.08~0.25W / m·K, and the strength is relatively balanced. Due to the large difference in dry bulk density and thermal conductivity between the two, t...
