Ultrahigh-strength shrinkage-free grouting material and preparation method thereof
The invention relates to the technical field of cement grouting materials, and discloses an ultrahigh-strength shrinkage-free grouting material, which is prepared from the following raw materials in parts by weight: 15% of concrete recycled blocks, 15% of cement, 25% of aggregate, 10% of polyamide, 10% of carbon fibers, 5% of alkaline solution (K0H, NaOH) and 20% of organic polymer emulsion. According to the preparation method of the ultrahigh-strength shrinkage-free grouting material, the strength of the grouting material is higher and the cement strength and the water-cement ratio are controlled through the reasonable mixing ratio of the raw materials and experiments, and a proper amount of polyamide and carbon fibers are added during preparation, so that the strength of the raw materials is conveniently increased through the raw materials during use; during use, the water-cement ratio of the cement to the grouting material and the proportion of the aggregate are changed, and the alkali-aggregate reaction mechanism is that the cement reaches a certain amount of soluble alkaline oxides (such as Na20 and Kz0) and chemically reacts with some mixing materials containing active minerals in the concrete under the moisture condition to generate gel; the high shrinkage and the strength of grouting are improved.
本发明涉及水泥灌浆料技术领域，且公开了一种超高强型无收缩灌浆料，包括以下重量份数配比的原料：混凝土再生块15％、水泥15％、骨料25％、聚酰胺10％、碳纤维10％、碱性溶液(K0H、NaOH)5％和有机聚合物乳液20％。该超高强型无收缩灌浆料制备方法，通过合理原料的配合比以及实验，使灌浆料的强度更高，控制水泥强度和水灰比，在制备时加入适量的聚酰胺以及碳纤维，方便在使用时通过该原料增加原料的强度，而且在使用时改变水泥和灌浆料的水灰比以及骨料的配比，碱骨料反应的机理碱骨料反应是水泥达到一定数量的可溶性碱性氧化物(如Na20、Kz0)与混凝土中某些含有活性矿物的参和料在有水分的条件下发生化学反应生成凝胶，提高灌浆的高收缩性以及强度。
