Bridge expansion joint anchoring area concrete and preparation method thereof
The invention discloses bridge expansion joint anchoring area concrete and a preparation method thereof, and relates to the technical field of bridge construction. The invention relates to a basalt fiber reinforced concrete, which is prepared from the following components in parts by weight: 2 to 4 parts of FERRO fiber, 3 to 6 parts of basalt fiber, 60 to 120 parts of steel fiber, 800 to 1000 parts of cementing material, 2000 to 2250 parts of basalt gravel, 1300 to 1600 parts of sand, 280 to 320 parts of water and 6 to 12 parts of additive, wherein the FERRO fiber reinforced concrete is prepared from the following components in parts by weight: 2 to 4 parts of FERRO fiber, 3 to 6 parts of basalt fiber, 60 to 120 parts of steel fiber, 800 to 1000 parts of cementing material, 2000 to 2250 parts of basalt gravel, 1300 to 1600 parts of sand, 280 to 320 parts of water and 6 to 12 parts of additive; the steel fibers are high-precision chopped steel fibers; the cementing material is a mixture of cement and lime, the weight percentage of the cement is 74%-84%, and the weight percentage of the lime is 16%-26%. According to the formula composed of the FERRO fiber, the basalt fiber, the steel fiber, the cementing material, the basalt gravel, the sand, the water and the additive, the toughness degree is high in the aspect of bending toughness of the concrete, the strength, durability and other engineering performance of the concrete are improved, and it is ensured that the fluidity, uniformity and texture of the concrete meet the design.
本发明公开了桥梁伸缩缝锚固区混凝土及其制备方法，涉及桥梁建筑技术领域。本发明包括FERRO纤维、玄武岩纤维、钢纤维、胶凝材料、玄武岩碎石、砂、水和外加剂，各组分的重量组份为：FERRO纤维2‑4份、玄武岩纤维3‑6份、钢纤维60‑120份、胶凝材料800‑1000份、玄武岩碎石2000‑2250份、砂1300‑1600份、水280‑320份和外加剂6‑12份；所述钢纤维为高精度短切钢纤维；所述胶凝材料为水泥和石灰的混合物，其中，水泥的重量百分比为74％‑84％，石灰的重量百分比为16％‑26％。本发明通过FERRO纤维、玄武岩纤维、钢纤维、胶凝材料、玄武岩碎石、砂、水和外加剂组成的配方，在混凝土抗弯韧性方面，韧性度较高，改善混凝土的强度、耐久性和其他工程性能，确保其流动性、均匀性和质地符合设计。
