Cement mortar and preparation process thereof

Abstract

The invention belongs to the technical field of cement mortar, and particularly relates to cement mortar and a preparation process thereof. The cement mortar comprises, by weight, 120-287 parts of cement, 30-150 parts of diatomite, 30-106 parts of fly ash, 20-80 parts of epoxy resin emulsion, 10-30 parts of polyethylene glycol, 100-206 parts of water, 10-50 parts of toughening agents and 10-50 parts of defoaming agents. The cement mortar has excellent mechanical property such as compressive strength and bending strength and better corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of cement mortar, and in particular relates to a cement mortar and a preparation process thereof. Background technique [0002] As we all know, cement mortar is an important building cementing material. It is usually silicate clinker made by mixing limestone, coal, iron powder and clay and other mineral materials, and then adding gypsum to the clinker and grinding become. In actual production, in order to ensure the strength of cement mortar, cement manufacturers use technical means to properly mix some mixed materials to achieve the purpose of saving mineral resources, reducing production costs and protecting the environment. The mixed materials are mainly some cheap slag, furnace Ash, fly ash, etc. However, these cement mortars can only meet general strength requirements. For buildings with high safety performance, when the toughness, crack resistance, impermeability, and corrosion resistance of cement m...

Problems solved by technology

[0006] In actual production, there are also many problems in mixing polymers with inorganic materials such as cement mortar. For example, the incompatibility between organic matter and inorganic materials makes the structure of polymers and the ratio of them to inorganic materials very critical when mixing; such as epoxy Resin has many advantages, such as good chemical stability, strong corrosion resistance, electrical insulation and low shrinkage, but the cement mortar prepared when it is used alone for cement mortar modification has disadvantages such as poor toughness and easy cracking.
