Grouting agent with ultralow water-binder ratio and preparation method thereof
The invention relates to the technical field of grouting agents, and discloses a grouting agent with an ultralow water-binder ratio and a preparation method thereof.The grouting agent is prepared from, by weight, 10-15 parts of plasticizer, 3-5 parts of stabilizer, 4-6 parts of water reducing agent, 6-8 parts of silica fume, 4-8 parts of magnesium oxide, 1-2 parts of steel bar corrosion inhibitor and 100-200 parts of cement; the polycarboxylic acid water reducer is powder obtained by drying a high-performance water reducer based on an advanced polycarboxylic acid polymer through a special process. According to the grouting agent with the ultra-low water-binder ratio and the preparation method of the grouting agent, the grouting agent can have the characteristics of high water-reducing rate and low mixing amount through the added water reducing agent, and the cost can be remarkably reduced, so that the grouting agent can be flexibly suitable for multiple processing scenes, and sedimentation and cracking of concrete mortar can be effectively avoided through the added plastic expanding agent; therefore, compactness and filling of the concrete mortar are ensured, and the concrete mortar has no corrosion effect on reinforcing steel bars.
本发明涉及压浆剂技术领域，且公开了一种超低水胶比的压浆剂及其制备方法，包括以下重量份数配比的原料：塑化剂10～15份、稳定剂3～5份、减水剂4～6份、硅灰6～8份、氧化镁4～8份、钢筋阻锈剂1～2份、水泥100～200份，所述减水剂4～6份为聚羧酸粉体减水剂，是以先进的聚羧酸聚合物为基础的高性能减水剂，经特种工艺干燥得到的粉体。该超低水胶比的压浆剂及其制备方法，通过添加的减水剂，可以使压浆剂具备减水率高，掺量低的特点，能显著降低成本，从而压浆剂可以灵活适用于多个加工场景，通过添加的塑性膨胀剂，可以有效避免混凝土砂浆的沉降与开裂，从而确保混凝土砂浆的密实、充盈，且对钢筋无腐蚀作用。
