Novel prestressed duct grouting material and preparation method thereof
The invention discloses a novel prestressed duct grouting material and a preparation method thereof. The novel prestressed duct grouting material is prepared from the following components in parts by weight: 62 to 68 parts of cement, 10 to 15 parts of phosphorus slag powder, 4 to 8 parts of rock debris, 2 to 3.5 parts of coal gangue powder, 5 to 6.5 parts of porous silica fume, 1 to 1.5 parts of macromolecular water-absorbent resin, 0.1 to 0.4 part of corrosion inhibitor, 0.2 to 0.4 part of modified polyvinyl alcohol fiber, 2 to 4 parts of water reducing agent and 0.1 to 1 part of defoaming agent. According to the prestressed duct grouting material prepared by the invention, the recycling of solid wastes is realized, the pollution of the wastes to the environment is reduced, the problems of large shrinkage and low early strength of the grouting material after coagulation are effectively solved, and the aims of improving the safety, mechanical property and durability of the structure are fulfilled.
本发明公开了一种新型预应力孔道压浆料及其制备方法，以重量份数计包括以下组分：62～68份的水泥，10～15份的磷渣粉，4～8份岩屑，2～3.5份煤矸石粉，5～6.5份的多孔微硅粉，1～1.5份的高分子吸水树脂，0.1～0.4份的阻锈剂，0.2～0.4份的改性聚乙烯醇纤维，2～4份的减水剂，0.1～1份的消泡剂；本发明制备的预应力孔道压浆料，实现了固体废弃物的回收利用，减少废弃物对环境的污染，有效的解决了浆液在凝结后收缩大的情况和早期强度低的问题，达到了提高结构的安全性、力学性能和耐久性的目的。
