Preparation method of concrete waterproofing agent
The invention discloses a preparation method of a concrete waterproofing agent. The preparation method comprises the following steps: mixing calcium sulfoaluminate and gypsum powder according to the mass ratio of (1: 7.5)-(1: 9), stirring to react, and stirring and mixing to obtain the calcium sulfoaluminate expanding agent which can effectively improve the internal structure of concrete, can plugcapillary channels in concrete by selecting gypsum powder as a raw material, the waterproofing agent can obviously improve the anti-seepage and waterproof functions of the concrete, has the effects of reinforcement, water reduction, crack resistance and the like, can improve the workability of the fresh concrete, obviously improves the working timeliness of the concrete, is suitable for anti-seepage and damp-proof engineering in the aspect of buildings and is suitable for large-scale popularization.
本发明公开了一种混凝土防水剂的制备方法，首先，将硫铝酸钙与石膏粉按质量比1：7.5～1：9混合，搅拌反应后，搅拌混合后，得硫铝酸钙膨胀剂，能够有效改良混凝土内部结构，其选用石膏粉作为原料，能够堵塞混泥土内部毛细孔通道，显著提高混凝土的抗渗防水功能，同时具有增强，减水、抗裂等功效，并可改善新拌混凝土的和易性，显著改善混凝土的工作时效性，适用于建筑方面的防渗防潮工程，适合大范围推广。
