Renewable-aggregate industrial mortar and preparation method thereof

Abstract

The invention discloses an industrial mortar using renewable aggregates as a main filling raw material and a preparation method of the industrial mortar. The production formula of the industrial mortar is that 10-30 percent of silicate cement, 10-20 percent of calcium oxide, 10-15 percent of renewable concrete aggregate of which particle size is smaller than or equal to 5 mm, 5-10 percent of renewable clay brick aggregate of which particle size is smaller than or equal to 5 mm, 2-3 percent of renewable glass aggregate of which particle size is smaller than or equal to 5 mm, 10-20 percent of natural yellow sand, 15-25 percent of coal ash, 4-6 percent of water-reducing agent and a proper quantity of water are adopted, wherein the water-reducing rate of the water-reducing agent is required to be greater than 12 percent; preferably, the formula does not contain other components. Through the process of the method, the cost is effectively reduced; the mortar can be used in building surfaces and wall surfaces for plastering, is conducive to improving thermal insulation performance and energy-saving level of buildings, and has higher pressure resistance and tensile strength compared with existing similar products.

Description

technical field [0001] The invention relates to an industrial mortar made of recycled aggregates, which has the characteristics of ecological environment protection and the advantages of heat preservation function. Background technique [0002] For a long time, construction waste with mineralization characteristics has not been well utilized as a resource in our country. Existing construction waste bricks and construction waste block technologies are extensive use of construction waste "currency", the products have no characteristics, and the technology lacks innovation, so the market rate of return is low. The scientific utilization of construction waste slag resources is classified utilization, and the different material properties of different construction waste slags are fully utilized to produce building materials with outstanding functions. [0003] my country's construction waste is mainly composed of waste concrete and waste bricks (walls), followed by a small amoun...
