Foam concrete block for building enclosure structure and preparation method thereof

Abstract

The invention discloses a foam concrete block for a building envelope and a preparation method thereof. The foam concrete block comprises the following raw materials by weight percent: 15-20% of ordinary Portland cement, 13-18% of fly ash, 13-18% of tailing powder, 15-20% of aerated block wastes, 1-2% of quick lime, 0.4-0.8% of modifying agent, 0.07-0.1% of foaming agent and 30-38% of water. The foam concrete block and the preparation method have the beneficial effects that the industrial wastes such as fly ash, tailing powder, aerated block wastes and the like are utilized, the waste mixing amount is more than 70%, and plenty of industrial solid wastes are turned into wealth, thus protecting the environment and saving the resources; the technological process is unique, the modifying agent is added, and autoclaved curing is omitted, so that the investment and energy consumption are low.

Description

technical field

[0001] The invention relates to a building material, in particular to a foam concrete block for a building envelope and a preparation method thereof. Background technique

[0002] According to the requirements of national new wall material development industry orientation, new wall material enterprises must speed up the transformation of economic development mode, promote the adjustment and optimization of industrial structure, and must follow the principles of technological innovation, comprehensive utilization of resources, energy conservation and environmental protection, and adapting measures to local conditions. Making full use of waste resources, adopting technological innovation, turning waste into treasure, and developing energy-saving, waste-recycling, and environmentally-friendly wall material products are in line with national industrial policies, and are the most urgent and important tasks for building a resource-saving and environment-friendly soc...
