Ultrahigh-performance seawater coral sand concrete and preparation method thereof
The invention discloses an ultra-high performance seawater coral sand concrete and a preparation method thereof, the ultra-high performance seawater coral sand concrete comprises cement, silica fume, fly ash, seawater, coral sand and a self-prepared admixture formed by mixing a polycarboxylic acid superplasticizer, a polyether shrinkage reducing agent and fatty acid salts. The coral sand is used as aggregate to replace traditional sand, the storage and transportation cost of concrete raw materials is reduced, the timeliness of raw material supply is guaranteed, and the prepared ultrahigh-performance seawater coral sand concrete is high in strength, good in volume stability and excellent in permeation resistance and can stably serve in a high-temperature, high-humidity and high-salt severe island environment for a long time.
本发明公开了一种超高性能海水珊瑚砂混凝土及其制备方法，其组分包含水泥，硅灰，粉煤灰，海水，珊瑚砂以及聚羧酸高效减水剂、聚醚类减缩剂、脂肪酸盐类混合的自配外加剂，本申请的方案以海水为拌合水替代传统的淡水，珊瑚砂为集料替代传统的砂料，降低了混凝土原材料的储运成本，保证了原料供应的时效性，制得的超高性能海水珊瑚砂混凝土强度高、体积稳定性好、抗渗透性能优异，能够长期稳定地在高温、高湿、高盐的恶劣海岛环境下服役。
