Cavitation-erosion-resistant abrasion-resistant agent for hydraulic concrete and preparation method of cavitation-erosion-resistant abrasion-resistant agent
The invention relates to the technical field of concrete admixtures, in particular to a hydraulic concrete cavitation-erosion-resistant abrasion-resistant agent which comprises the following raw materials in parts by weight: 1-50 parts of floating beads, 1-50 parts of a magnesium oxide expanding agent, 1-50 parts of a polycarboxylate superplasticizer, 1-35 parts of sodium silicate, 1-20 parts of sodium abietate, 1-20 parts of a nano anti-cracking and anti-seepage agent and 1-20 parts of latex powder. According to the cavitation-erosion-resistant and abrasion-resistant agent for the hydraulic concrete and the preparation method of the cavitation-erosion-resistant and abrasion-resistant agent for the hydraulic concrete, the floating beads, the magnesium oxide expanding agent, the polycarboxylic acid water reducing agent, the sodium silicate, the sodium abietate, the nano anti-cracking and anti-seepage agent, the latex powder and the water are mixed and prepared; by equivalently replacing 3-5% of cement with the hydraulic concrete cavitation-erosion-resistant abrasion-resistant agent, the abrasion resistance of the concrete can be improved by 3-5 times, the dry shrinkage rate is greatly reduced, the anti-permeability grade is improved by 3-5 grades, the cracking resistance is greatly improved, and the service life of the concrete is prolonged.
本发明涉及混凝土外加剂技术领域，具体为一种水工混凝土耐空蚀抗冲磨剂，包括以下重量份数配比的原料：漂珠1～50份，氧化镁膨胀剂1～50份，聚羧酸减水剂1～50份，硅酸钠1～35份，松香酸钠1～20份，纳米抗裂防渗剂1～20份，乳胶粉1～20份。该水工混凝土耐空蚀抗冲磨剂及其制备方法，通过漂珠、氧化镁膨胀剂、聚羧酸减水剂、硅酸钠、松香酸钠、纳米抗裂防渗剂、乳胶粉和水的混合配置，在配制水工混凝土耐空蚀抗冲磨混凝土时，用这种水工混凝土耐空蚀抗冲磨剂等量取代3～5％的水泥，可提高混凝土抗冲磨强渡3～5倍，干缩率大幅度降低，抗渗等级提高3～5个等级，抗开裂性能大幅度提高，增加其使用寿命。
