Self-crystallization grouting material for repairing concrete cracks and preparation method of self-crystallization grouting material
The invention provides a self-crystallization grouting material for repairing concrete cracks and a preparation method thereof, and relates to the field of crack repairing, the self-crystallization grouting material is prepared from the following raw materials: superfine Portland cement, superfine sulphoaluminate cement, tetra calcium aluminoferrite, dicalcium silicate, a capillary crystalline material and an auxiliary agent; wherein tetracalcium aluminoferrite and dicalcium silicate are formed by calcining raw materials of limestone, shale, silica and pyrite at high temperature. According to the invention, the crystal permeable product is composed of Portland cement, aggregate and a soluble silicate mixture, and some adjuvants are added at the same time to relieve the degree of chemical reaction between soluble silicate and free calcium; soluble silicate can chemically react with free calcium in a concrete structure to generate calcium silicate crystals, and the calcium silicate crystals are insoluble in water and block capillary pores in a structural layer with a certain depth like plugs, so that the water tightness of the structure and a coating is improved, the waterproof effect is achieved, and the overall sealing effect of concrete is guaranteed.
本发明提供一种混凝土裂缝修补用自结晶型灌浆材料及其制备方法，涉及裂缝修补领域，由如下原料制成：超细硅酸盐水泥、超细硫铝酸盐水泥、铁铝酸四钙、硅酸二钙、渗透结晶材料和辅助剂；其中铁铝酸四钙和硅酸二钙由石灰石、页岩、硅土、黄铁矿石的原料高温煅烧加工而成。本发明中，结晶渗透型产品是由硅酸盐水泥、骨料和可溶性硅酸盐混合物组成的，同时加入一些辅助剂来缓解可溶性硅酸盐与游离钙发生化学反应的程度；可溶性硅酸盐能与混凝土结构中的游离钙发生化学反应生成硅酸钙晶体，这些硅酸钙晶体是不溶于水的，它们就象塞子一样，将一定深度结构层中的毛细孔堵塞，提高结构和涂层的水密性，达到防水的效果，保证混凝土的整体密封效果。
