Low-temperature early-strength tunnel lining filling material
The invention belongs to the technical field of special cement-based materials, and particularly relates to a low-temperature early-strength tunnel lining filling material. The material is prepared from the following components in parts by mass: 30-45 parts of quick-hardening cement, 4-10 parts of superfine admixture, 40-50 parts of quartz powder, 0.5-0.8 parts of a water reducing agent, 3-8 parts of an anti-freezing agent, 0.1-0.4 parts of a plastic expanding agent, 0.05-0.1 parts of a slurry stabilizer, 0.03-0.06 parts of an anti-foaming agent and 1-5 parts of a reinforcing component. The components are uniformly mixed, water is added for stirring, the water-material ratio is 0.15-0.18, and tunnel lining filling construction can be performed after slurry is uniform. The material is suitable for rapid construction of tunnel lining filling under the condition of low temperature (0 DEG C to -20 DEG C), and has the advantages of high workability, early strength, high strength, micro-expansion, good anti-freezing effect and the like. The material can be directly mixed and used in a low-temperature environment lower than 0 DEG C without adding construction procedures, the strength can be rapidly developed, the construction efficiency and the engineering quality are ensured, and the material is suitable for popularization and application.
本发明属于特种水泥基材料技术领域，具体涉及一种低温早强型隧道衬砌填充材料，由以下质量份数比的组分配制而成：快硬水泥30～45份、超细掺合料4～10份、石英粉40～50份、减水剂0.5～0.8份、防冻剂3～8份、塑性膨胀剂0.1～0.4份、浆体稳定剂0.05～0.1份、消泡剂0.03～0.06份、增强组分1～5份。将上述各组份均匀混合，加水搅拌，水料比0.15～0.18，浆体均匀后即可进行隧道衬砌填充施工。本发明适用于低温(温度0℃～零下20℃)条件下隧道衬砌填充的快速施工，具有高和易性、早强高强、微膨胀和防冻效果好等优点；低于0℃的低温环境下可以直接拌合使用，无需增加施工工序，强度能快速发展，保证施工效率和工程质量，适合推广应用。
