Rapid-hardening steel slag mortar capable of being constructed by spraying

Abstract

The invention provides rapid-hardening steel slag mortar capable of being constructed by spraying. The rapid-hardening steel slag mortar is composed of the following components in percentage by mass: 40%-70% of steel slag, 10%-30% of ordinary silicate cement, 0-30% of natural sand, 0.02%-0.1% of 3mm-7mm shortly-cut polypropylene fibers, 0.02%-0.2% of a water-retaining agent additive which is metered by being compared with the ordinary silicate cement, 1%-10% of a redispersible latex powder additive which is metered by being compared with the ordinary silicate cement, and 2%-5% of a rapid hardening agent additive which is metered by being compared with the ordinary silicate cement; and the water-ash ratio of the mortar is 0.1-0.3. The rapid-hardening steel slag mortar has the characteristics of high anti-cracking performance, rapid construction speed and the like.

Description

technical field [0001] The invention belongs to a building material, in particular to a quick-setting steel slag mortar that can be sprayed and constructed, which can be applied to the surface material of the steel wire frame cement polystyrene sandwich wall, and can also be used for thin plastering exteriors with similar functional requirements. Anti-crack mortar for external wall insulation system and other fields. Background technique [0002] At present, Portland cement concrete is widely used in infrastructure construction as an inexpensive building material. However, the production of 1 ton of Portland cement requires about 1.5 tons of limestone and a large amount of coal, oil and other fuels or electric energy; at the same time, the production of 1 ton of cement clinker will release about 1 ton of carbon dioxide. The Portland cement industry has been considered It is one of the industries with high energy consumption and serious environmental pollution, so it has att...

Problems solved by technology

This method has less wet work on site and faster construction speed, but it is greatly affected by the transportation distance, is easily damaged during transportation, and is more expensive

The other is to prepare only polystyrene panels for steel wire grids in the factory and carry out construction on site. This method is convenient for transportation and low in cost, but there are many wet operations on site, and the maintenance time is long, and the construction efficiency is low.
