Problems solved by technology

The mortar in the prior art is mostly prepared with cement as the cementitious material. The strength of the mortar mainly depends on the cement grade and the amount of cement. If the grade of cement is too high, the insufficient amount of cement will lead to poor water retention, so the dependence on cement is strong.

Abstract

The invention provides a mortar. The mortar takes industrial solid waste steel slag powder with different particle sizes and an aggregate forming agent composed of industrial solid wastes as main rawmaterials, and steel slag with the particle size of about 1 mm can play a skeleton role, so that the strength of the mortar is improved, the heat resistance of the mortar is improved, the mortar is ensured to have relatively high strength in a using process, various stress effects can be borne, and cracks are avoided; gaps of 1 mm steel slag can be filled with the steel slag with the particle sizeof 150 [mu]m, so that the density of the mortar is increased, and the strength of the mortar is further enhanced; and the steel slag with the particle size of 100 [mu]m improves the uniform stabilityof the mortar. The mortar provided by the invention does not contain cement, the dependence of the mortar on the cement is reduced, meanwhile, the burden of industrial solid wastes on the environmentis solved, and the obtained mortar has the characteristics of uniformity and stability, small layering degree, high bonding strength, excellent frost resistance and low shrinkage value.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a mortar and a preparation method thereof. Background technique [0002] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials such as cement, lime paste, clay, etc. and water. Commonly used mortars are cement mortar, mixed mortar, lime mortar and clay mortar. Mortar is used for masonry and plastering projects, and can be divided into masonry mortar and plastering mortar. The former is used for masonry and component installation of bricks, stones, blocks, etc.; the latter is used for walls, floors, roofs and Plastering on the surface of beam and column structures to meet protection and decoration requirements. Some of the ordinary mortar materials are gypsum, lime plaster or clay mixed with fibrous reinforcing materials and water to prepare a paste, which is called ash, paste, mud or ...
