Wind power high-strength grouting material and preparation method thereof
The invention discloses a wind power high-strength grouting material and a preparation method thereof. The wind power high-strength grouting material comprises 35-45 parts of cement, 35-45 parts of fine aggregate, 7-20 parts of a superfine mineral admixture, 3-7 parts of an inorganic expanding agent, 0.02-0.05 part of a hybrid plastic expanding agent, 0.2-0.4 part of a water reducing agent and 0.04-0.06 part of a defoaming agent, wherein the inorganic expanding agent is a magnesium oxide-calcium sulphoaluminate binary inorganic expanding agent, and the hybrid plastic expanding agent is formed by intercalating montmorillonite into a nitroso compound. During preparation, the cement, the fine aggregate and the superfine mineral admixture are mixed and stirred to prepare powder A; then the inorganic expanding agent, the hybrid plastic expanding agent, the water reducing agent and the defoaming agent are mixed and stirred to prepare powder B; and finally the powder A and the powder B are mixed and stirred. The grouting material disclosed by the invention can be used for filling the whole space and quickly forming without inserting, tamping and compacting during construction, and is stable in later strength, free from shrinkage, slightly expanded in volume and tightly connected with equipment.
本发明公开了一种风电高强灌浆料及其制备方法，包括水泥35‑45份，细集料35‑45份，超细矿物掺合料7‑20份，无机膨胀剂3‑7份，杂化塑性膨胀剂0.02‑0.05份，减水剂0.2‑0.4份及消泡剂0.04‑0.06份，无机膨胀剂为氧化镁‑硫铝酸钙二元无机膨胀剂，杂化塑性膨胀剂为亚硝基化合物插层蒙脱土而成。制备时先将水泥、细集料和超细矿物掺合料混合搅拌制得粉料A，再将无机膨胀剂、杂化塑性膨胀剂、减水剂和消泡剂混合搅拌制得粉料B，最后将粉料A和粉料B混合搅拌即可。本发明的灌浆料能够在施工时无需插捣振实即可填充全部空间并迅速成型，且后期强度稳定无倒缩，体积微膨胀，与设备连接紧密。
