Abstract

This invention relates to a method for preparing heat-preservation mortar utilizing solid castoffs, in which, the raw material is composed of two groups: group A includes the following components and weight percentage: slag powder 20-40%, powdered coal ash 20-30%, Portland cement 30-40%, Ca reinforcing agent 5-15%, abandon polystyrene foams 3-8%, PP fiber 0.05-0.15%, re-dispersible latex powder 1-3%, water preservation agent 0.2-0.6%, water reducer 0.1-0.5%, defoamer 0.05-0.10%, and quartz sand is the raw material of group B, and the weight ratio of group A and B is 1:1. Raw materials of group A are weighed and matched then to be put into a sterring mill and mixed uniformly and then quartz sand of equal volume is added in it to be mixed continuously to get the heat preservation mortar, which can be used by adding suitable volume of water.

Description

technical field [0001] The invention relates to a method for preparing thermal insulation mortar by utilizing solid waste, and belongs to the technical field of comprehensive utilization of chemical building materials and waste residues. Background technique [0002] The extensive use of thermal insulation materials with excellent performance and scientific thermal insulation technology in building materials will achieve good social and economic benefits. [0003] Insulation mortar is made of some materials with better thermal insulation properties as aggregate, together with cementitious materials, additives, and water, and is made into mortar for wall insulation in a certain proportion. The traditional thermal insulation mortar uses expanded perlite as the aggregate, but due to the high water absorption rate of expanded perlite, high brittleness, low bond strength, and poor crack resistance, it cannot meet the performance requirements of modern buildings for thermal insula...
