Abstract

The invention discloses an aerated concrete product and a production method. The invention is characterized in that: the aerated concrete product is made from the common silicate cement as raw material, instead of industrial solid waste as raw material in the prior art; and the method comprises the steps of weighing, stirring, grouting, curing, demoulding, cutting, steam curing, naturally drying and test. The aerated concrete product has the advantages of ultra-light weight, high strength, simple fabrication, low energy consumption, and low capital investment. The invention realizes the weight reduction of wall materials and greatly increases the construction efficiency.

Description

technical field [0001] The invention relates to an air-entrained concrete product and its processing technology, which belongs to the technology of building materials. Background technique [0002] At present, aerated concrete has a development history of 40 years in our country. According to incomplete statistics, there are 596 production enterprises in the country, with a total design capacity of more than 46.5 million cubic meters. It has become the main energy-saving wall material and the only one. A wall material that can meet the design standard with a single material is in line with the sustainable development strategy. However, the market share of aerated concrete in my country's wall materials is not high, which has a great relationship with its large investment in production equipment, high energy consumption, high application cost, and high labor intensity of workers. Contents of the invention [0003] The purpose of the present invention is to overcome the def...
