Preparation method of polypropylene fiber reinforced high-performance coral sand concrete
The invention discloses a preparation method of polypropylene fiber reinforced high-performance coral sand concrete. The strength grade of the high-performance coral sand concrete reaches C120 or above, and the high-performance coral sand concrete is prepared from the following materials: cement, fly ash, silica fume, coral sand, ground blast furnace slag powder, quartz powder, seawater, a water reducing agent which is a cement and mineral admixture, a defoaming agent and high-performance polypropylene fibers. The coral sand is prepared by controlling the pre-wetting time of the coral sand, the proportion of mineral admixtures, a proper additive and a stirring form and short-term seawater high-temperature accompanying culture. The polypropylene-reinforced high-performance coral sand concrete disclosed by the invention has high mechanical property, good impermeability, compactness and durability, and overcomes the defects of low strength, high brittleness, poor flowability, large mechanical index dispersion and the like of common coral concrete. The preparation method is simple, convenient and easy to implement, has important economic value and significance for ocean resource development and island national defense facility construction, and meets ocean requirements.
本发明公开了一种聚丙烯纤维增强高性能珊瑚砂混凝土的制备方法。所述高性能珊瑚砂混凝土强度等级达到C120以上，材料包含：水泥、粉煤灰、硅灰、珊瑚砂、磨细高炉矿渣粉、石英粉末、海水、减水剂为水泥和矿物掺合料，消泡剂，高性能聚丙烯纤维。采用控制珊瑚砂预湿时间、矿物掺合料配比、合适的外加剂及搅拌形式及短期海水高温伴养进行制备。本发明的聚丙烯增强高性能珊瑚砂混凝土除了具有较高力学性能，同时具有良好的抗渗性、致密性和耐久性，填补了普通珊瑚混凝土强度低、脆性大、流动性差、力学指标离散大等众多缺陷。原材料就地取材、制备方法简便易实现，对海洋资源开发和岛礁国防设施建设有重要经济价值和意义，符合海洋需求。
