Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a concrete foaming insulation brick and a preparation method thereof. Background technique [0002] With the popularization of building energy saving and the continuous improvement of people's demand for the comfort of living environment, thermal insulation materials have been paid more and more attention by people. As one of the house insulation materials, the room temperature non-fired foam brick is more and more popular because of its heat preservation, sound insulation, fire prevention, and strength superior to traditional insulation materials. However, the existing foamed bricks on the market have shortcomings such as relatively high capacity, poor impact resistance, relatively high water absorption, high brittleness, and relatively poor durability. [0003] Chinese invention patent application 201010562916.8 discloses a magnesium cement foam material...
