Production process of autoclaved aerated concrete block
The invention relates to the technical field of concrete blocks, in particular to a production process of autoclaved aerated concrete blocks, which comprises the following steps: S1, feeding raw materials into a ball mill for dry grinding treatment, and feeding the raw materials into a raw material bin for storage for later use; s2, the raw material powder, the aluminum powder suspension and purified water are fed into a stirring machine to be stirred and mixed, the diffusion degree of materials in the stirring machine is measured to reach 21 cm to 22 cm, the temperature of the stirring machine is increased to 48 DEG C to 50 DEG C, and blank slurry is obtained; s3, anti-cracking fiber nets are laid in a mold box layer by layer, then the blank slurry is poured into a mold, and the mold box filled with the blank slurry is moved to a static curing room for static gas generation; s4, after static curing and gas forming are finished, the blank is placed in a drying oven at the temperature of 65-68 DEG C to be pre-cured for 2-2.5 h, and when the compressive strength of the blank reaches 0.75 MPa, the mold box and the blank are conveyed into a cutting machine through a traveling crane. According to the autoclaved aerated concrete block manufacturing method, the problems that an existing autoclaved aerated concrete block is large in drying shrinkage value and low in strength can be effectively solved.
本发明涉及混凝土砌块技术领域，尤其为一种蒸压加气混凝土砌块的生产工艺，包括以下步骤：S1，将原料送入球磨机中进行干磨处理，并送入原料仓中存放备用；S2，将原料粉末、铝粉悬浮液以及纯净水送入搅拌机中进行搅拌混合，测量搅拌机中的物料扩散度达到21cm‑22cm，将搅拌机的温度上升到48℃‑50℃，得到胚体浆料；S3，将防裂纤维网逐层铺设在模具箱内，再向模具中倒入胚体浆料，将浇注满胚体浆料的模具箱移动到静养间进行静止发气；S4，静养发气结束，胚体置于温度为65℃‑68℃的烘箱中预养2h‑2.5h，待胚体抗压强度达到0.75MPa时，使用行车将模具箱和坯体送至切割机中，本发明可以有效解决目前蒸压加气混凝土砌块具有干燥收缩值大、强度低的问题。
