High-strength shrinkage-free grouting material and production method thereof
The invention relates to the technical field of building materials, and particularly discloses a high-strength shrinkage-free grouting material and a production method thereof. Comprising the following raw materials in parts by weight: 40-80 parts of cement, 30-60 parts of aggregate, 0.1-0.8 part of an expanding agent, 1-5 parts of a water reducing component, 0.2-1 part of an early strength component, 0.2-1 part of a water retention component, 1-2 parts of a thickening agent, 2-3 parts of a retarder, 2-3 parts of a shrinkage reducing agent and 2-3 parts of a defoaming agent, the aggregate is selected from high-strength quartz sand, the SiO2 content is greater than or equal to 95%, the cement is preferably selected from ordinary Portland cement or sulphoaluminate cement, and the defoaming agent is preferably selected from ordinary Portland cement or sulphoaluminate cement. Wherein 1 part of coal ash, 1 part of mineral powder and 1 part of silica fume are added. According to the high-strength shrinkage-free grouting material and the production method thereof, the compressive strength 1-3 days after grouting can reach 30-60 MPa or above, the strength 28 days after grouting can reach 60-120 MPa, all gaps can be filled, the requirement of secondary grouting of equipment is met, close contact between the equipment and a foundation can be guaranteed, shrinkage is avoided after secondary grouting, and the bonding strength is high.
本发明涉及建筑材料技术领域，具体公开了一种高强度无收缩灌浆料及其生产方法，包括以下重量份数配比的原料：水泥40‑80份、骨料30‑60份、膨胀剂0.1‑0.8份、减水组分1‑5份、早强组分0.2‑1份、保水组分0.2‑1份、增稠剂1‑2份、缓凝剂2‑3份、减缩剂2‑3份和消泡剂2‑3份，骨料选用高强石英砂，其中SiO2含量≥95％，水泥优选普通硅酸盐水泥或硫铝酸盐水泥，其中添加有粉煤灰、矿粉和微硅粉各1份。该高强度无收缩灌浆料及其生产方法，灌浆后1‑3天的抗压强度可达30‑60Mpa以上，28天强度60‑120兆帕，且可填充全部空隙，满足设备二次灌浆的要求，可以保证设备与基础之间紧密接触，二次灌浆后无收缩，粘结强度高。
