Dry-mixed waterproof mortar prepared from modified ceramic polishing powder and preparation method of dry-mixed waterproof mortar
The invention relates to the technical field of concrete admixtures, in particular to dry-mixed waterproof mortar prepared from modified ceramic polishing powder and a preparation method of the dry-mixed waterproof mortar. The invention discloses dry-mixed waterproof mortar prepared from modified ceramic polishing powder. The dry-mixed waterproof mortar is prepared from the following raw materials: ordinary Portland cement, the modified ceramic polishing powder, machine-made sand, redispersible latex powder, a water-retaining and thickening material and a water repellent, the modified ceramic polishing powder is obtained by modifying ceramic polishing powder through a coupling agent and nano silicon oxide. The ceramic polishing powder is modified by the coupling agent, so that harmful pores of the mortar can be effectively filled, the waterproof mortar is more compact, the water retention capacity of the waterproof mortar can be improved, the defects of influencing the strength and permeability of the mortar can be effectively overcome, the activity index of the ceramic polishing powder can be improved, and the service life of the ceramic polishing powder is prolonged. The generation of cement hydration products is promoted, and the comprehensive performance of the waterproof mortar, especially the strength performance and the anti-permeability performance, can be greatly improved.
本发明涉及混凝土外加剂技术领域，特别涉及一种利用改性陶瓷抛光粉制备的干混防水砂浆及其制备方法，其中，一种利用改性陶瓷抛光粉制备的干混防水砂浆原料包括普通硅酸盐水泥、改性陶瓷抛光粉、机制砂、可再分散乳胶粉、保水增稠材料和憎水剂；所述改性陶瓷抛光粉为陶瓷抛光粉经过偶联剂和纳米氧化硅改性处理得到。本发明通过偶联剂改性陶瓷抛光粉，不仅能够有效填充砂浆的有害孔隙，使防水砂浆更为密实，可提高防水砂浆的保水性能，而且还能够有效克服影响砂浆的强度、渗透性能的缺陷，同时能够提高陶瓷抛光粉的活性指数，促进水泥水化产物的生成，可大幅提升防水砂浆的综合性能，特别是强度性能和抗渗性能。
