High-strength grouting material and preparation method thereof
The invention relates to the technical field of grouting materials, in particular to a high-strength grouting material and a preparation method thereof.The high-strength grouting material is prepared by mixing 20-35 parts of Portland cement, 25-40 parts of fine sand, 5-12 parts of mineral powder, 3-10 parts of a fiber mixture, 2-5 parts of silica fume, 1-5 parts of glass beads, 1-2 parts of a water reducing agent, 1-2 parts of an early strength agent, 0.1-1 part of a defoaming agent and 0.1-0.5 part of an expanding agent through a stirrer, portland cement, fine sand, mineral powder, a fiber mixture and silica fume are used as main materials, glass beads, a water reducing agent, an early strength agent, a defoaming agent and an expanding agent are used as main auxiliary materials, scientific compatibility is adopted, and the prepared grouting material is good in impact strength, tensile strength and bending strength and outstanding in foam inhibition performance and has the advantages that the early strength develops rapidly, the later strength is continuously increased, and the service life of the grouting material is prolonged. The grouting material has the characteristics of good initial fluidity, strong tendon holding capability, difficult cracking, good grouting compactness and the like.
本发明涉及灌浆料技术领域，其具体是一种高强度灌浆料及其制备方法,本发明采用硅酸盐水泥20～35份、细沙25～40份、矿粉5～12份、纤维混合物3～10份、微硅粉2～5份、玻化微珠1～5份、减水剂1～2份、早强剂1～2份、消泡剂0.1～1份、膨胀剂0.1～0.5份由搅拌机混合制得，以硅酸盐水泥、细沙、矿粉、纤维混合物和微硅粉作为主料，以玻化微珠、减水剂、早强剂、消泡剂和膨胀剂作为主要辅料，采用科学配伍，配制的灌浆料抗冲击强度、抗拉强度、抗弯强度性能好，抑泡性能突出，具有早期强度发展迅速，后期强度持续增长，初始流动性好，握筋能力强，不易开裂，灌浆的密实性好等特点。
