AI Technical Summary

Problems solved by technology

Due to a series of factors such as the inherent defects of the raw materials used and the inaccurate measurement control of this traditional construction lime mortar, the quality of the construction mortar is low, which often leads to leakage of the walls of residential buildings, water leakage of the roof, sanding and cracking of the walls, etc. Phenomenon
In addition, building lime paste mixed mortar not only occupies the site but also seriously pollutes the environment in the application of building construction.

Abstract

The invention discloses green and environmental-friendly thermal-insulation dry powder mortar which comprises the following substances in parts by weight: 20-40 parts of cement, 50-70 parts of quartz sand, 5-8 parts of fine ash, 2-8 parts of glazed hollow beads, 0.2-0.5 part of inorganic fiber and 2-25 parts of ash-calcium powder. The mortar disclosed by the invention has the characteristics of being good in workability, high in caking ability with base materials, good in heat-preserving and heat-insulating properties and good in fireproof performance.

Description

Technical field: [0001] The invention relates to the technical field of building mortar, in particular to a green and environment-friendly thermal insulation dry powder mortar. Background technique: [0002] At present, the mortar applied to wall construction, interior and exterior wall painting, and plastering in construction engineering basically all adopts a mixed mortar mixed with lime plaster or lime powder in cement mortar. Due to a series of factors such as the inherent defects of the raw materials used and the inaccurate measurement control of this traditional construction lime mortar, the quality of the construction mortar is low, which often leads to leakage of the walls of residential buildings, water leakage of the roof, sanding and cracking of the walls, etc. Phenomenon. In addition, building lime paste mixed mortar not only occupies the site but also seriously pollutes the environment in the application of building construction. Invention content: [0003] ...
