Embodiment Construction
[0021] The application will be described in further detail below.
[0022] The embodiment of the present application discloses a production process for an autoclaved aerated concrete block, including S1, weighing, weighing according to the proportion of raw materials, adding elastic short fibers into the raw materials, and in this embodiment, the elastic short fibers are made of polymer amide-66;
[0023] S2, pulping, first put the raw materials other than the elastic short fibers into the mixer and add an appropriate amount of water to stir into a slurry, then the slurry is transported through a fiber silo, and the elastic short fiber raw materials are pumped into by the wind into the fiber silo, and then naturally and evenly fall on the surface of the slurry, and before the elastic short fiber is input into the fiber silo, it passes through a discharge chamber, so that the elastic short fiber raw material is electrostatically charged;
[0024] S3, enter the mold, first set ...

The application discloses a production process of autoclaved aerated concrete blocks, and relates to the technical field of autoclaved aerated concrete blocks. The technical scheme is a production process of autoclaved aerated concrete blocks, including S1, weighing, weighing according to the ratio of raw materials; S2, pulping, putting the raw materials into a mixer and adding an appropriate amount of water to stir to form a slurry; S3, enter the mold, pour the slurry into the mold; S4, cut, after resting for a period of time, pour the autoclaved aerated concrete block into the mold and cut it into the required size; S5, steam curing, autoclave the cut The aerated concrete blocks are put into the steam curing vehicle for steam curing; S6, stacking, the finished autoclaved aerated concrete blocks are stacked and stored, and in the step S3, before the slurry is poured into the mold, it is set in the mold The pre-stretched elastic fiber strands are poured into the slurry so that the slurry pours the elastic fiber strands inside. The present application has a reasonable structure and can effectively reduce the amount of cracks on the autoclaved aerated concrete blocks.
Description
technical field [0001] The application relates to the technical field of autoclaved aerated concrete blocks, in particular to a production process of autoclaved aerated concrete blocks. Background technique [0002] Autoclaved aerated concrete blocks are made of fly ash, lime, cement, gypsum, slag, etc. as the main raw materials. A porous concrete product made of high-pressure steam curing and other processes, mainly used as building wall materials. [0003] Autoclaved aerated concrete block, as a new type of building wall material, has low energy consumption and environmental protection, which is in line with national policy standards. However, autoclaved air-entrained concrete blocks have problems of large drying shrinkage and low strength. In the process of forming the structural strength of the autoclaved aerated concrete block, many micro-cracks are often generated due to the plastic shrinkage of the green body, so that in the later autoclaving process, the micro-crac...
