Concrete mortar for repairing bridge expansion joints and preparation process of concrete mortar
The invention relates to the technical field of bridge building materials, in particular to concrete mortar for repairing bridge expansion joints and a preparation process of the concrete mortar. The concrete mortar is prepared from the following components in parts by weight: 350 to 450 parts of Portland cement, 20 to 50 parts of sulphoaluminate cement, 5 to 15 parts of mineral powder, 10 to 25 parts of silica fume, 20 to 50 parts of fly ash, 450 to 550 parts of quartz sand, 10 to 30 parts of tackifier, 4 to 8 parts of composite fiber, 2 to 4 parts of water reducing agent, 0.5 to 1.0 part of retarder, 0.3 to 0.5 part of defoaming agent and 80 to 120 parts of water. The Portland cement and quick-hardening sulphoaluminate cement composite cementing material is used as a main body, the mineral powder, the silicon powder and the fly ash are used as additives, the quartz sand is used as a filler, and the tackifier, the composite fibers and other auxiliaries are added, so that the prepared concrete mortar has excellent early and later strength performance and also has excellent impact resistance.
本发明涉及桥梁建筑材料技术领域，具体为一种桥梁伸缩缝修补用混凝土砂浆及其制备工艺。所述混凝土砂浆包括以下重量组分：硅酸盐水泥350‑450份、硫铝酸盐水泥20‑50份、矿粉5‑15份、硅灰10‑25份、粉煤灰20‑50份、石英砂450‑550份、增粘剂10‑30份、复合纤维4‑8份、减水剂2‑4份、缓凝剂0.5‑1.0份、消泡剂0.3‑0.5份、水80‑120份。本发明以硅酸盐水泥和快硬硫铝酸盐水泥复合胶凝材料作为主体，以矿粉、硅粉、粉煤灰为外加剂，以石英砂为填料，再加入增粘剂、复合纤维及其他助剂，制备的混凝土砂浆具有出色的早期和后期强度表现，同时具有优异的抗冲击性能。
