Embodiment

[0029] This embodiment provides a production process for high-quality autoclaved aerated concrete slabs, including the following steps:

[0030] S1, preparation stage;

[0031] A. Weigh the following raw materials according to the specified weight parts; silica sand 50.7, gypsum 4, cement 18, lime 9.3; and add the above-mentioned materials to the stirring tank and continue to add quantitative water according to the water-material ratio of .06 for stirring. Obtain the preparatory mixing material;

[0032] B. Process the steel bar into a sheet-like steel mesh through the automatic networking device, and at the same time dip the steel frame in wax, and detachably install the steel mesh on the steel frame through the steel bar connecting frame to form a steel cage, and then The steel cage is antirust treated by dipping and drying;

[0033] C. Clean up the ferry pouring vehicle, oil the inner wall of the ferry pouring vehicle, and put the steel cage into the ferry pouring vehicle...

Abstract

The invention discloses a production process of an autoclaved aerated concrete slab with a high superior product rate, and belongs to the technical field of building material processing and production. The autoclaved aerated concrete slab is prepared from the following raw materials in parts by mass: 49-52 parts of silica sand, 3.5-5 parts of gypsum, 18-21 parts of cement, 9-12 parts of lime and water, and the preparation stage, the pouring molding stage, the demolding cutting stage and the slotting steam curing stage are subjected to process optimization respectively, so that the problem thatthe superior product rate is relatively low in the process of producing the autoclaved aerated concrete slab in the current process is effectively solved.

Description

technical field [0001] The invention relates to the technical field of building material processing and production, in particular to a production process for high-quality autoclaved aerated concrete slabs. Background technique [0002] Autoclaved aerated concrete panels (referred to as aerated panels, AAC panels), as a combined assembly building material, have been widely promoted and applied in China because of their economical, convenient construction and environmentally friendly production characteristics. The production of cement, lime, silica sand and other raw materials needs to be fully mixed into a slurry, and then poured into a trolley with steel mesh sheets for pouring and molding. After the pouring car is formed into a whole piece of concrete structure, it will be cut into certain pieces. The size of the specification; and this prefabricated building material has also issued relevant standards for its density and strength. For example, the national standard for th...
