Preparation method of aerated block concrete
The invention discloses a preparation method of aerated block concrete, and particularly relates to the technical field of concrete preparation, adopted silica fume can fill pores in the concrete, so that the compactness of the concrete is improved, pore spaces for alkali aggregate reaction in the concrete are reduced, the occurrence of alkali aggregate reaction is slowed down or prevented, and the service life of the concrete is prolonged. Wherein silicate has high chemical activity and can chemically react with alkaline substances in the concrete to form stable silicate gel, alkali erosion can be effectively resisted, silicon dioxide in the silica fume can react with alkaline oxides in the concrete to generate silicate and water, part of the alkaline substances are consumed in the process, and the silicate gel can effectively resist alkali erosion. The reaction speed of the alkali aggregate is slowed down; the adopted high-temperature-resistant water reducing agent reduces moisture in the concrete under the high-temperature condition, the high-temperature-resistant performance of the concrete is improved, the alkali corrosion resistance and the high-temperature-resistant performance of the aerated concrete are improved, and the aerated concrete is suitable for large-scale application and popularization.
本发明公开了一种加气块混凝土制备方法，具体涉及混凝土制备技术领域，采用的硅灰可以填充混凝土中的孔隙，从而提高混凝土的密实度，有助于减少混凝土内部可供碱骨料反应的孔隙空间，减缓或防止碱骨料反应的发生，其中的硅酸盐具有较高的化学活性，可以与混凝土中的碱性物质发生化学反应，形成稳定的硅酸盐凝胶，可有效抵抗碱侵蚀，硅灰中的二氧化硅可以与混凝土中的碱性氧化物反应，生成硅酸盐和水，过程会消耗掉一部分碱性物质，减缓碱骨料反应的速度；且采用的耐高温减水剂在高温条件下减少混凝土中的水分，提高混凝土的耐高温性能，使加气混凝土的抗碱侵蚀和耐高温性能得到提升，适合大范围推广使用。
