Abstract

The invention provides dry-mixed mortar prepared from industrial solid waste. The dry-mixed mortar is characterized by being prepared from materials in parts by weight as follows: 100 parts of cement, 300-400 parts of river sand, 50-100 parts of steel slag, 0-50 parts of iron mine tailings, 0-50 parts of glass powder, 1-2 parts of an interface reinforcing agent, 1-2 parts of an exciting agent, 0.1-0.5 parts of a water retaining agent, 1-2 parts of a water reducing agent and 0.1-0.3 parts of reinforcing fibers. According to the dry-mixed mortar, the industrial solid waste is fully utilized as aggregate to replace natural river sand, environmental protection is facilitated, resource recycling is realized, and meanwhile, performance such as the freezing resistance, the permeability resistance and the like of the dry-mixed mortar is improved through addition of the industrial solid waste.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a dry-mixed mortar prepared from industrial solid waste. Background technique [0002] As one of the main building materials in civil engineering, mortar is mainly composed of cement, medium-coarse sand aggregate, water and some external admixtures. Construction mortar has the characteristics of wide application and huge market demand. However, with the rapid development of my country's infrastructure, the medium-coarse sand aggregate resources that can be used as mortar materials in some areas of the country are decreasing day by day, and the price of raw materials is increasing year by year, which even affects the development of local infrastructure. Therefore, it is of great engineering significance to research and develop new mortar aggregates with large supply and stable performance. [0003] Waste glass, tailings sand and steel slag are bulk industri...
