Abstract

The invention discloses a lightweight thermal-insulation concrete, which is composed of the following raw materials in parts by weight: 70 to 120 parts of cement, 20 to 30 parts of lime, 20 to 80 parts of sand, 30 to 50 parts of coal slag, 25 to 55 parts of aluminium metallurgy slag, 40 to 80 parts of polypropylene fiber, 40 to 70 parts of foaming agent, and 50 to 90 parts of water; wherein the foaming agent is composed of plant-origin fatty acid, and is very safe. The provided concrete has the advantages of cheap raw materials, simple production technology, lightweight, thermal insulation property, energy saving, and environment-friendliness.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a lightweight heat-preserving concrete. Background technique [0002] With the diversification and detailing of modern people's life concepts and ways, the requirements for the environment in buildings are also increasing. While HVAC brings people a comfortable and high-quality living environment, it has also become a major player in building energy consumption. The poor insulation effect of building walls will further increase the use of HVAC, which will cause waste of energy consumption. The use of traditional concrete to build the walls of buildings not only increases the load of the building itself, but also greatly increases the labor intensity and increases the project cost. With the increasingly prominent energy problems, the country pays more and more attention to building energy conservation, and the level of building energy efficiency directly affects my ...
