High-elasticity-modulus grouting material and preparation method thereof
The invention provides a high-elasticity-modulus grouting material and a preparation method thereof. The high-elasticity-modulus grouting material comprises the following components in parts by weight: 740-780 parts of ordinary Portland cement, 100-110 parts of mineral powder, 70-100 parts of silica fume, 40-60 parts of an expanding agent, 40-60 parts of microbeads, 950-1000 parts of quartz sand, 8-10 parts of a polyacid water reducing agent, 0.3-0.5 part of a plastic expanding agent, 0.8-1 part of a defoaming agent and 7.5-10 parts of an early strength agent. The prepared high-elasticity-modulus grouting material has good constructability and ultrahigh elasticity modulus, is suitable for fixation and installation of various large important equipment, foundation reinforcement of onshore and offshore wind turbines and anchoring of anchor rods, and has the advantages of high strength, high elasticity modulus, high flowability, high durability, slight expansion and the like.
本发明提出了一种高弹性模量灌浆料及其制备方法，其组成和重量分数如下：普通硅酸盐水泥740～780份、矿粉100～110份、硅灰70～100份、膨胀剂40～60份、微珠40～60份、石英砂950～1000份、聚酸酸减水剂8～10份、塑性膨胀剂0.3～0.5份、消泡剂0.8～1份、早强剂7.5～10份。本发明制备的高弹性模量灌浆料具有良好的施工性和超高的弹性模量，适用于各种大型重要设备的固定和安装、陆上及海上风机基础加固、锚杆锚固，具有高强度、高弹性模量、大流动性、高耐久性、微膨胀等优点。
