Thermal insulation bearing wall brick and preparation method thereof

Abstract

This invention relates to a thermal insulation load-bearing wall brick and its preparation method, belonging to a manufacturing technology field of building material with load-bearing property and thermal and heat insulation double properties. The main raw materials include (by weight parts) portland cement 100, small stones 70-90, and ball-shaped glass microbeads 15-35, desulfurized gypsum with intensifier 10-25, and fly ash 10-30. The method has the advantages of reasonable designed formula, simple manufacture, small thermal conductivity coefficient, and large compressive strength. As thermal insulation and protection are combined, therefore reducing transmission phenomenon between hot and cold and having good thermal insulation effect and simple operation. In addition, raw materials can be found on the site, resources can be reused and cost is low.

Description

technical field [0001] The invention relates to a thermal insulation load-bearing wall brick and a preparation method thereof, and belongs to the technical field of manufacturing building materials with dual performances of external wall load-bearing and thermal insulation. Background technique [0002] At this stage, in the construction of construction projects, the country prohibits the use of clay bricks, and more concrete block bricks are used, but one of the disadvantages of concrete block single bricks is that the shrinkage rate is greater than 0.4%, and the overall wall shrinkage rate is greater than 0.25%, so Its shrinkage stability is poor and it is easy to crack. The second disadvantage is that it lacks the function of heat preservation and heat insulation, and the effect of energy saving cannot be achieved. In order to achieve the effect of thermal insulation, it is necessary to re-do the thermal insulation project, resulting in a longer construction period and i...

[0002] At this stage, in the construction of construction projects, the country prohibits the use of clay bricks, and more concrete block bricks are used, but one of the disadvantages of concrete block single bricks is that the shrinkage rate is greater than 0.4%, and the overall wall shrinkage rate is greater than 0.25%, so Its shrinkage stability is poor and it is easy to crack

The second disadvantage is that it lacks the function of heat preservation and heat insulation, and the effect of energy saving cannot be achieved.

In order to achieve the effect of thermal insulation, it is necessary to re-do the thermal insulation project, resulting in a longer construction period and increased investment
