Abstract

The invention discloses foaming cement which comprises the following components in percentage by mass: 30-45% of cement, 5-10% of ceramic brick polishing powder, 1-4% of a foaming component, 0.1-1% of a foam stabilizing component, 0.5-2% of a waterproof component, 0.5-2% of a reinforcing component and the balance water, wherein cement is composed of silicate cement and aluminate cement in a mass ratio of (5-10) to 1. The foaming cement disclosed by the invention has the characteristics of high strength, good waterproof performance, good thermal insulation effect, good durability and the like; and a great deal of ceramic brick polishing powder further can be comprehensively utilized, so that social resources are saved, using efficiency is improved, and economic benefits and social benefits are remarkable.

Description

technical field [0001] The invention belongs to the technical field of building energy conservation, and in particular relates to foamed cement. Background technique [0002] According to statistics, the heating energy consumption of buildings in my country is three times that of developed countries with similar climatic conditions. In order to improve the thermal insulation function of buildings, adding insulation layers to buildings is an important measure for building energy conservation. It is made of polystyrene board, extruded board, polyurethane and other organic materials, but organic insulation materials have disadvantages such as flammability and aging. Foamed cement is an inorganic thermal insulation material, which has the advantages of light weight, non-combustibility, thermal insulation, and the same lifespan as the building, and has a good application prospect. [0003] Foamed cement is mainly formed by introducing air bubbles through chemical or physical foam...
