Preparation process of high-strength autoclaved sand aerated concrete plate
The invention discloses a preparation process of a high-strength autoclaved aerated concrete plate. According to the high-strength autoclaved aerated concrete slab and the preparation method thereof, firstly, the red pillars, the sillimanite and the kyanite which are weighed in the step S1 are mixed and then added into a crushing ball mill, grinding is started, reinforced stone particles are obtained, the kyanite and the andalusite are added into the raw materials of the high-strength autoclaved aerated concrete slab, and the high-strength autoclaved aerated concrete slab is obtained. Kyanite and andalusite can be converted into mullite during combustion, the firing shrinkage of the product is balanced by expansion accompanied by the mullite, and finally the matrix is densified. As the kyanite and the andalusite are added into the aerated concrete plate, the temperature of a softening-under-load starting point of a product added with the kyanite and the andalusite is increased, and the creep resistance is improved, so that the physical property of the aerated concrete plate is improved, the aerated concrete plate is not easy to damage or creep in the use process, the durability of the aerated concrete plate in the subsequent use process is improved, and the service life of the aerated concrete plate in the subsequent use process is prolonged.
本发明公开了一种高强度蒸压砂加气混凝土板材制备工艺。本发明中，先将步骤S1中称取好的红柱、硅线石和蓝晶石，将其混合好之后，加入到粉碎球磨机的内部，开始对其进行研磨，得到加强石颗粒料，在高强度蒸压砂加气混凝土板材的原料内部添加了蓝晶石、红柱石，蓝晶石、红柱石在燃烧时会转化为莫来石伴随的膨胀平衡了制品的烧成收缩,最终使基质致密化。因而添加蓝晶石、红柱石的制品荷软开始点温度上升,抗蠕变性能得到提高，从而提高了该加气混凝土板材的物理性能，使得其在使用过程中不会轻易发生破损或者蠕变，从而增加了该加气混凝土板材后续使用过程中的耐用度和使用寿命。
