Ternary early strength grouting material, preparation method and application thereof
The invention relates to the technical field of building structure reinforcement, in particular to a ternary early strength grouting material as well as a preparation method and application thereof. The invention discloses a ternary early strength grouting material, which is prepared from the following raw materials in parts by weight: 100 parts of a ternary cementing material, 1.54 to 2.3 parts of an early strength agent, 0.3 to 1 part of a retarder, 0.8 to 2 parts of a water reducing agent, 30 to 40 parts of water and 5 to 15 parts of polymer emulsion. According to the ternary early-strength grouting material disclosed by the invention, a ternary early-strength gelling system is modified by utilizing the polymer emulsion, and a high-molecular polymer in the polymer emulsion is cross-linked with a ternary early-strength hydrolyzed product-ettringite (AFt) and alumina gel (AH3) to form a network structure, so that the compactness and the flexibility of the grouting material can be effectively improved; in addition, due to the property of the organic matter of the polymer, the interface bonding strength of the grouting material and a matrix asphalt mixture can be improved, and the cracking resistance of the grouting asphalt mixture can be improved.
本发明涉及建筑结构加固的技术领域，具体涉及一种三元早强灌浆料、制备方法及其应用；本申请公开了一种三元早强灌浆料，包括下述重量份的原料：三元胶凝材料100份，早强剂1.54‑2.3份，缓凝剂0.3‑1份，减水剂0.8‑2份，水30‑40份，聚合物乳液5‑15份。本申请所述的一种三元早强灌浆料，利用聚合物乳液对三元早强胶凝体系进行改性，聚合物乳液中的高分子聚合物与三元早强水解后的产物‑钙矾石(AFt)与铝胶(AH3)互相交联成为网络状结构，可以有效地提高灌浆料的密实度与柔韧性，再加上聚合物本身有机物的属性，能提升灌浆料与基体沥青混合料的界面粘结强度，有利于提高灌浆沥青混合料的抗开裂能力。
