Green environment-friendly building mortar and preparation method thereof

Abstract

The invention provides a green environment-friendly building mortar and a preparation method thereof, and relates to the technical field of building materials, wherein the building mortar is preparedfrom the following raw materials in parts by weight: 30-45 parts of building waste, 40-50 parts of Portland cement, 20-30 parts of a steel slag micro-powder, 15-20 parts of a water slag micro-powder,1-1.3 parts of aminosulfonate, 1-3 parts of calcium chloride, 1-2 parts of aluminum oxide clinker, 1.5-2 parts of cellulose ether, 0.5-1 part of emulsified silicone oil, 0.3-0.5 part of modified waterborne epoxy resin, 1-1.5 parts of polypropylene fibers, 1-1.3 parts of regenerated rubber, 1-2 parts of zinc stearate, 0.5-1 part of aluminum hydroxide, 1.5-4 parts of glass microbeads, 2-3 parts of alkali lime, 0.2-0.4 part of higher fatty acid, 0.1-0.3 part of rosin resin, 1-2 parts of an admixture, and 8-10 parts of water. The preparation method of the green environment-friendly building mortarincludes four steps; the green environment-friendly building mortar has the properties of heat preservation, heat insulation, noise reduction, sound insulation, fire prevention, water prevention, lowenergy consumption and moisture prevention, has good durability, mechanical properties and mechanical strength, and has better economic benefits and environment-friendly functions.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a green and environment-friendly building mortar and a preparation method thereof. Background technique [0002] Construction mortar is a kind of ready-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed by the production enterprise, which is used to construct the building surface insulation layer a building material. [0003] With the development of the modern construction industry, the use of mortar is increasing rapidly. Among them, the important component of mortar is natural river sand, which is a non-renewable resource. With the rapid development of the construction industry, the consumption of river sand is increasing year by year. The output is getting less and less, and natural river sand is facing an increasingly scarce situation; mountain rock resources are excavated in large ...

Problems solved by technology

According to statistics, there are more than 45 million tons of construction waste produced and discharged by construction in my country every year; most of the construction waste is disposed of by open-air stacking or landfill, causing environmental pollution, and 80% of construction waste The above are bricks and concrete fragments, they have not been used very well
