Capillary crystalline repair mortar suitable for humid environment and preparation method thereof
The invention discloses permeable crystallization type repair mortar suitable for a humid environment and a preparation method of the permeable crystallization type repair mortar. The permeable crystallization type repair mortar comprises cement, dried sand, silica fume, sodium silicate, basalt fibers, an alkali activator, polybutylene terephthalate, brucite, hydroxyplatinic acid and cellulose ether. The preparation method comprises the following steps: firstly, adding the cement, the silica fume, the basalt fiber, the cellulose ether, the PBT and the hydroxyplatinic acid into a container, and uniformly stirring and mixing to obtain fiber mixed powder; adding dried sand and brucite into the mixed powder, and uniformly stirring and mixing to obtain a mixture; and completely dissolving potassium hydroxide in water to prepare an alkaline excitation solution, adding the alkaline excitation solution and sodium silicate into the mixture, stirring, mixing and reacting to prepare the repair mortar. According to the repair mortar disclosed by the invention, on the basis of cement mortar, sodium silicate with a permeation function is introduced, so that not only are the compression resistance and breaking strength of the mortar improved, but also the compactness, cracking resistance and waterproofness of the mortar are improved, internal and external dual waterproof effects are formed, and the adaptability of the repair mortar in a humid environment is improved.
本发明公开了一种适用于潮湿环境的渗透结晶型修补砂浆及其制备方法，包括水泥、烘干砂、硅灰、硅酸钠、玄武岩纤维、碱激发剂、聚对苯二甲酸丁二醇酯、水镁石、羟铂酸、纤维素醚；制备时先将水泥、硅灰、玄武岩纤维、纤维素醚、PBT、羟铂酸加入容器中，搅拌混合均匀，制得纤维混合粉料；并向该混合粉料中加入烘干砂和水镁石，搅拌混合均匀，制得混合料；再将氢氧化钾完全溶解于水中配制成碱性激发溶液，将该碱性激发溶液和硅酸钠加入上述混合料中，搅拌混合反应，制得该修补砂浆。本发明的修补砂浆基于水泥砂浆的基础上，通过引入具有渗透功能的硅酸钠，不仅提高了砂浆的抗压、抗折强度，且提高砂浆的密实性、防开裂性和防水性，形成内部和外部的双重防水功效，提高了该修补砂浆于潮湿环境下的适应性。
