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.

Description

technical field [0001] The invention relates to a masonry mortar for thermal insulation masonry based on aerated concrete slag and a preparation method thereof. Background technique [0002] The existing self-insulating masonry or wall masonry mortar is generally used for ordinary mortar masonry, and some special mortar is used for masonry, but this type of mortar has a large thermal conductivity and poor thermal insulation performance. Or it is easy to form a cold and heat bridge in the wall, which reduces the overall thermal insulation performance of the self-insulating masonry or the wall. Contents of the invention [0003] In view of the above situation, the object of the present invention is to provide a kind of masonry mortar for thermal insulation masonry based on aerated concrete slag, which can make full use of discarded aerated concrete block slag, and can save a large amount of raw material resources, It can also reduce the production cost, shorten the producti...
