Abstract

The invention provides foam dry-mixed mortar with high water permeability, high heat dissipation and thawing and freezing resistance. The foam dry-mixed mortar with the high water permeability, the high heat dissipation and the thawing and freezing resistance comprises regenerated building aggregate, regenerated mineral aggregate, regenerated fiber materials, cement, water retaining agents, water reducing agents, adhesive and thickening agents. The regenerated building aggregate comprises building concrete and brick slag. The regenerated mineral aggregate comprises industrial mineral waste including silicon dioxide, aluminium sesquioxide, ferroferric oxide, titanium dioxide, magnesium oxide and calcium oxide. The regenerated fiber materials comprise industrial textile waste including natural fibers, chemical fibers and regenerated fibers. The foam dry-mixed mortar has the advantages that concrete prepared from the prepared foam dry-mixed mortar is made of different types of industrial building waste, is large in porosity, good in water permeability and heat dissipation, high in strength, easy to maintain and clean and wide in application range and has diversified colors.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a foaming dry powder mortar with high water permeability, high heat dissipation and anti-freezing and a preparation method thereof. Background technique [0002] Construction mortar is widely used in projects such as masonry, plastering, repairing, grouting and pasting of facing materials. It is one of the most used building materials in construction projects. The main materials of construction mortar are cement and sand. With the development of China's basic construction, the amount of mortar used in construction continues to increase, and a large amount of construction waste will be generated in the process of urbanization, which not only wastes natural resources, but also destroys the ecological environment, pollutes the environment, and affects the ecological balance. Therefore, green building mortar has become a research hotspot. [0003] Green building mortar ...
