Production method of aerated concrete plate

Abstract

The invention relates to the technical field of concrete plates, in particular to an aerated concrete plate, and provides a production method of the aerated concrete plate. The production method comprises the production steps of raw material preparation, steel bar processing, steel bar mesh assembling, batching, pouring, still standing, cutting, autoclaved curing and taking out of a kettle. Aerated concrete is porous silicate concrete manufactured in the modes that a siliceous material and a calcareous material serve as main raw materials, a gas forming agent is doped, water is added for stirring, pores are formed through a chemical reaction, and the technological processes such as pouring molding, pre-curing cutting and steam curing are conducted. The concrete plate obtained through the technological method is low in weight and good in heat insulation performance, harmful gas is not emitted, and processibility is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete slabs, in particular to an aerated concrete slab. Background technique [0002] Air-entrained concrete is a kind of porous silicate concrete. Its various physical and mechanical properties depend on the concrete structure after autoclaving, including the composition of pore structure and pore wall. [0003] Like ordinary Portland concrete, the composition of the pore wall of air-entrained concrete is determined by the type and quantity of a series of hydration products generated during the hydrothermal treatment of calcareous materials and siliceous materials, which also makes air-entrained concrete Concrete has certain physical and mechanical properties. [0004] The pore structure of air-entrained concrete not only has the microporous structure like ordinary Portland concrete, but also the pores formed by aluminum powder, which have a great influence on the physical and mechanical properties o...

Problems solved by technology

[0009] The raw materials of air-entrained concrete enterprises in my country are quite different, the process technology routes are not the same, and the scale and technology are very different, which determines the importance of practical experience in guiding the production process. However, if you do not study the theory of air-entrained concrete in depth, you will inevitably be rigid Due to the existing experience, it limits the improvement of our production and management level
