Permeable crystallization type waterproof agent doped in concrete
The invention is applicable to the technical field of concrete waterproofing agents, and provides a concrete internally-doped permeable crystallization type waterproofing agent which comprises the following components: rice hull ash, modified diatomite, nano aluminum oxide, calcium sulfate, sodium aluminate, sodium methyl silicate, sodium polyacrylate, polyvinyl alcohol, sodium sulfate and sodium bicarbonate. In order to solve the problems of poor effect of most concrete waterproofing agents, low concrete repairing and healing rate and no repeated impermeability, the finished product obtained in the invention can improve the strength, the impermeability and the internal compactness of the concrete, the concrete structure can be automatically repaired and healed under the action of crystallization even if the concrete structure is locally damaged and leaked (the crack is less than 0.6 mm), and the concrete waterproof agent has the repeated impermeability and can be used for repairing and healing the concrete. The waterproof agent is prepared from the rice hull ash, so that fissure seepage caused by unstable size of a common concrete structure is essentially changed, the waterproof agent has a permanent waterproof effect, and the waterproof agent takes the rice hull ash as one of the main components, is environment-friendly and economical, and saves the cost.
本发明适用于混凝土防水剂技术领域，提供了一种混凝土内掺渗透结晶型防水剂，包括以下组成成分：稻壳灰、改性硅藻土、纳米氧化铝、硫酸钙、铝酸钠、甲基硅酸钠、聚丙烯酸钠、聚乙烯醇、硫酸钠、碳酸氢钠，相对于现有技术中，混凝土防水剂效果大多差，混凝土修补愈合速率慢，不具备多次抗渗能力的问题，本发明中所得成品能够提升混凝土强度、抗渗性能及内部密实度，混凝土结构即使局部受损渗漏(裂缝小于0.6mm)在结晶作用下，会自行修补愈合，并具有多次抗渗能力，从而在本质上改变了普通混凝土结构体积不稳定而再次带来的裂渗，具有永久的防水效果，而且防水剂以稻壳灰为主要成分之一，环保经济，节约了成本。
