Efficient thixotropic agent for tunnel lining concrete and preparation method of efficient thixotropic agent
The invention provides an efficient thixotropic agent for tunnel lining concrete and a preparation method of the efficient thixotropic agent. The efficient thixotropic agent is prepared from the following raw materials in parts by mass: 10-20 parts of a long-acting dispersing agent, 20-60 parts of water, 0.5-2.5 parts of a thickening agent, 0.4-1 part of sulfate, 0.4-1 part of carbonate, 0.6-1.2 parts of a defoaming agent and 4-8 parts of nano powder. The efficient thixotropic agent is excellent in thixotropic effect and high in thixotropic effect retention capacity, stirred concrete is good in flowing property, the setting time of the concrete is not affected, the segregation problem caused by large-altitude-difference free falling, long-term vibration and the like can be effectively solved, and the pouring efficiency and the construction quality of tunnel lining concrete are guaranteed.
本发明提供一种隧道衬砌凝土用高效触变剂及其制备方法。所述高效触变剂按下列质量份数的原料组成：长效分散剂10～20份、水20～60份、增稠剂0.5～2.5份、硫酸盐0.4～1份、碳酸盐0.4～1份、消泡剂0.6～1.2份、纳米粉体4～8份。该高效触变剂的触变效果优异，触变效果保持能力强，搅拌后的混凝土流动性能好，且对混凝土的凝结时间无影响，可有效解决大高差自由下落、长期振捣等导致的离析问题，保证隧道衬砌混凝土的灌注效率和施工质量。
