Subway segment lining grouting material
The invention belongs to the technical field of grouting materials, and particularly relates to a subway segment lining grouting material, which is prepared from the following ingredients in parts by weight: 485-600 parts of cement, 230-330 parts of ground slag, 375-500 parts of high-aluminum clinker, 950-1120 parts of gravel, 50-70 parts of modified carbon fibers, 4-8 parts of a water reducing agent, 1.5-3 parts of a retarder, 20-40 parts of zinc sulfate, 60-80 parts of a polymer emulsion and 120-200 parts of water. According to the subway segment lining grouting material, fine aggregate in the grouting material is replaced with the high-aluminum clinker, and the corrosion resistance of subway segments can be remarkably improved; meanwhile, the ground slag and the modified carbon fibers are matched, so that the strength of the grouting material can be effectively improved; the bonding strength among all the components can be improved by adding the polymer emulsion; and all the substances cooperate with one another to improve the strength of subway segments and improve the corrosion resistance.
本申请属于灌浆料技术领域，具体涉及一种地铁管片衬砌灌浆料，包括如下重量份的各组分：水泥485‑600份、磨细矿渣230‑330份、高铝熟料375‑500份、碎石950‑1120份、改性碳纤维50‑70份、减水剂4‑8份、缓凝剂1.5‑3份、硫酸锌20‑40份、聚合物乳液60‑80份、水120‑200份。本申请的地铁管片衬砌灌浆料，采用高铝熟料代替灌浆料中的细骨料，可显著改善地铁管片的耐腐蚀性能，同时配合磨细矿渣和改性碳纤维，可有效提高灌浆料的强度，聚合物乳液的加入有利于提高各组之间的粘接强度，各物质相互配合提高地铁管片的强度，改善耐蚀性能。
