Aerated concrete equipment used to produce blocks needs various raw materials, and each raw material can be used for different varieties. What kind of raw materials are used in factory production mainly depends on local resources, products produced and factory production, technology and equipment conditions.

　According to the basic functions of various raw materials in the production process of aerated concrete equipment, it can be divided into four categories. Namely: basic component materials, gas generating materials, conditioning materials and structural materials. 1. The basic component materials are siliceous materials and calcareous materials; Gas generating materials refer to gas generating agents and bubble stabilizers; The adjustment materials include a gas generation process regulator and an autoclave process regulator; Structural materials include steel bars and steel preservatives.

　　In the production process of aerated concrete equipment, other different auxiliary materials can also be used according to the technological needs and the specific conditions of each production equipment.

　　In the static hardening process of aerated concrete block blank, the hardening effect is different from that of non-thermal insulation. If the temperature of the blank disappears rapidly, for example, if there is no heat insulation in winter in the north, the blank will not only be greatly affected by the hardening speed, but also shrink and sink seriously. Therefore, at present, all factories tend to use heat insulation and stop facilities to ensure the solidification speed and uniformity of billets.

　　The cutting machine used in aerated concrete equipment mainly divides and visualizes the aerated concrete body to meet the shape requirements of aerated concrete products. The cutting process embodies the characteristics of aerated concrete, such as easy mass forming, easy separation, flexible appearance, meeting the needs of different uses and large-scale mechanization. It is also an aerated concrete which is different from other concrete.

　　In the process of selecting and using raw materials, we should fully grasp the basic function of the whole raw materials, and its main sand provides the whole siliceous material, not the process of reacting with calcium of calcareous materials to generate hydration products and contribute to the strength of the whole product. Raw sand can also be used as skeleton, and the whole raw material needs to reduce the shrinkage of the whole concrete. The second is quicklime, which needs to provide effective calcium oxide and can combine with silicon dioxide in the siliceous material of the material to generate considerable hydration products, thus forming the strength of the whole product. Lime can also provide alkalinity, which makes it angry with aluminum paste. When lime is hydrated, it needs physical heat release to promote the hardening of the whole body. Cement, on the other hand, needs to provide calcareous materials to contribute to the strength of sand aerated concrete. The main function of cement is the castability stability of the whole material.

　　The strength of the whole set of coffin plasticity when accelerating the hardening and cutting of the whole coffin. Then there is gypsum: it contributes to the strength of the whole coffin. Because calcium sulphoaluminate hydrate and the gel of the whole material are naturally generated during the static stopping process of the whole material, the bearing capacity of the temperature difference stress and humidity difference stress naturally occurring in the autoclaving process of the whole material body is continuously enhanced. But also can rapidly improve the strength of the whole product, reduce the shrinkage of the whole material and improve the frost resistance of the whole product. Promote the speed of the natural fuel hydration reaction of the whole material, promote the transformation of the whole Tobermole conversion stone, and form strength.。

　　And the generation of pomegranate seeds in the whole material makes the shrinkage value of the whole material decrease continuously. It can also slow down the thickening speed of slurry, slow down the setting speed of the whole cement, and dissolve the whole lime to quickly reduce the solubility of lime, and the temperature of the whole material needs to be reduced as soon as possible.

　　It can also slow down the thickening speed of slurry, delay the setting speed of the whole cement, and reduce the solubility of lime, and the temperature of the whole material needs to be reduced quickly, which is the summary process of the basic function of raw materials for aerated block equipment.

　　As autoclaved aerated concrete block is a non-load-bearing product, it mainly acts as a filler wall, which will not affect the safety of the whole construction project, and its quality is generally ignored. Moreover, the demand for autoclaved aerated concrete blocks in many areas is in short supply. Many production enterprises are tempted by profits. In order to reduce costs, they unilaterally pursue rapid production and high output, shorten the maintenance period without authorization, and use outdated production equipment and technology with less investment, resulting in extremely unstable product quality of aerated concrete blocks and high product failure rate. For example, in 2013, Guizhou Provincial Bureau of Quality and Technical Supervision conducted supervision and spot checks on the product quality of autoclaved aerated concrete block manufacturers in the province, and a total of 40 batches of samples from 40 enterprises were spot-checked. Only 25 batches were qualified, and the comprehensive batch pass rate was only 62.5%. In 2014, Guizhou Provincial Bureau of Quality and Technical Supervision once again conducted supervision and spot check on the product quality of autoclaved aerated concrete block manufacturers in the province, and randomly checked 47 batches of samples from 47 enterprises, and 37 batches were qualified, and the comprehensive batch pass rate was only 78.7%. Autoclaved aerated concrete products, as one of the most used new wall materials, affect the whole new wall material industry and the downstream construction industry. It is necessary to improve the production quality of autoclaved aerated concrete blocks.

　The most effective way to improve the production quality of autoclaved aerated concrete blocks is to use advanced technology and equipment. For most normal production enterprises, the technology and equipment have been fixed. If the improvement is carried out, it will cost a lot, and it will be restricted by many factors such as the site. This is more suitable for newly-built enterprises. The most feasible way to improve the quality of normal production enterprises is to strengthen production quality management and improve the level of production quality management.

　　Autoclaved aerated concrete block is a widely used new wall material, and manufacturers should pay attention to product quality. By improving quality management, we can not only improve product quality, but also reduce the production cost of enterprises and improve economic benefits.
