Preparation method of high-strength autoclaved aerated concrete
The invention relates to a preparation method of high-strength autoclaved aerated concrete, and belongs to the technical field of building materials. The preparation method comprises the following steps: roughening the surface of basalt fiber by adopting acetic acid, modifying the surface roughened basalt fiber by virtue of vinyltriethoxysilane and isopropyl triisostearoyl titanate, and adding nano aluminum oxide to prepare the modified basalt fiber for the high-strength autoclaved aerated concrete. Basalt fibers are doped to improve the microstructure of the autoclaved aerated concrete and effectively block a water seepage channel in the concrete, so that the autoclaved aerated concrete shows good shrinkage cracking resistance, a large amount of fibers distributed in the miscellaneous direction form a complex three-dimensional system in the concrete, and the strength of the autoclaved aerated concrete can be effectively improved.
本发明涉及一种高强度蒸压加气混凝土的制备方法，属于建筑材料技术领域。本发明采用乙酸对玄武岩纤维表面进行粗化处理，再通过乙烯基三乙氧基硅烷和三异硬脂酰基钛酸异丙酯对表面粗化玄武岩纤维进行改性，并添加纳米氧化铝，制备用于高强度蒸压加气混凝土的改性玄武岩纤维，玄武岩纤维的掺入可以改善蒸压加气混凝土的微观结构，有效堵塞混凝土内部的渗水通道，使蒸压加气混凝土表现出良好的抗收缩开裂能力，杂向分布的大量纤维在混凝土内部形成了复杂的三维体系，可以有效提高蒸压加气混凝土的强度。
