Abstract
The invention discloses an aerated concrete debris-based masonry mortar for thermal-insulation masonry and a preparation method thereof. According to the invention, aerated concrete block broken waste which is used as a base material undergoes crushing and screening to prepare a mortar aggregate-lightweight sand dry powder; and cement, pure water and a micro-foaming agent are added in proportion to prepare a hydraulic gelled composition. By the above technical scheme, the defect that various mortars for present self-insulation wall masonry has large heat conductivity coefficient and poor thermal insulation performance, it is easy to form cold/heat bridge effect in masonry walls and the overall thermal insulation performance of self-insulation walls is reduced is overcome. The masonry mortar provided by the invention is suitable for thermal insulation masonry or wall masonry, is more suitable for self-insulation masonry or wall masonry, and also can be used for troweling, plastering and seaming.
