Low-slump polycarboxylic acid super-retarding water reducing agent and production method thereof
The invention provides a polycarboxylic acid super-retarding water reducing agent with small slump and a production method thereof, and relates to the technical field of building materials, the polycarboxylic acid super-retarding water reducing agent comprises the following raw materials by weight: 10%-33% of a polycarboxylic acid water reducing agent, 60% of water, 0.3%-3% of a polydimethylsiloxane montmorillonite nano composite material, and 0.05%-0.12% of a reducing agent. By using the water-retaining agent, the water-retaining performance of the concrete is better, the slump change amplitude of the concrete at different temperatures is reduced, the defoaming agent and the transfer agent are used for adjusting the water-reducing rate of the concrete and are matched with the water-retaining agent, the slump change amplitude of the concrete at different temperatures is further reduced, and the initial setting time of the concrete is prolonged by the retarder; and the finished product of the water reducing agent has good workability and flow retentivity, so that the application range of the water reducing agent in small-slump concrete engineering is widened, the production process is simple, the reaction conditions are easy to control, and environmental pollution is avoided.
本发明提供一种塌落度小的聚羧酸超缓凝减水剂及其生产方法，涉及建筑材料技术领域，包括如下重量份的原料：聚羧酸减水剂10%～33%、水60%、聚二甲基硅氧烷蒙脱土纳米复合材料0.3%～3%、还原剂0.05%～0.12%。通过保水剂的使用，使混凝土的保水性能更好，减少混凝土在不同温度下坍落度变化幅度，消泡剂、转移剂调节混凝土的减水率，与保水剂相配合，进一步减少混凝土在不同温度下坍落度的变化幅度，缓凝剂延长了混凝土的初凝时间，提高减水剂的市场竞争力，成品减水剂具有良好的和易性和流动保持性，从而拓宽了在小坍落度混凝土工程中的应用，其生产工艺简单，反应条件容易控制，无环境污染。
