Laying dry powder in new type

Abstract

A dried masonry powder as a novel cementing material for building is prepared from powdered coal ash, russet mud, activator, lime, gypsum and early strengthening agent through proportional mixing, grinding and sieving. It advantage is stable performance.

Description

Technical field: [0001] The invention relates to a building material, in particular to a new dry masonry powder produced by a non-high-temperature method using bulk solid wastes such as fly ash, red mud, and construction waste. Background technique: [0002] In the construction of construction projects, the on-site configuration of construction mortar has the defects of unstable quality, poor workability and high cost, which leads to slow construction speed, poor quality of masonry, and affects the seismic performance of the structure. In addition, sand, lime, and cement are piled up in the open air and mixed on site, causing mutual pollution of the materials themselves and pollution of the environment, which affects the civilized construction level of construction companies. Invention content: [0003] The purpose of the present invention is to provide the technology of producing new type of masonry dry powder for construction by non-high-temperature method based on bulk ...
