Ultrahigh-strength whole coral sand seawater geopolymer concrete and preparation method thereof
The invention discloses ultrahigh-strength whole coral sand seawater geopolymer concrete and a preparation method thereof. The concrete is prepared from the following components in percentage by mass: 40 to 45 percent of industrial waste residue, 1 to 3 percent of alkali activator raw material, 10 to 15 percent of seawater, 40 to 45 percent of coral sand and 0.2 to 0.5 percent of high-performance water reducing agent. According to the ultrahigh-strength geopolymer concrete, rich marine resources such as seawater and coral sand are fully utilized, slag, fly ash and silica fume are excited by an alkali activator to form a cementing material with a compact structure to prepare the ultrahigh-strength geopolymer concrete, the local material utilization rate reaches 45-55%, the high cost generated by remote transportation of fresh water and river sand is reduced, and the service life of the ultrahigh-strength geopolymer concrete is prolonged. In addition, consumption of natural resources such as fresh water and river sand is effectively relieved, and damage to the ecological environment in the river sand excavation process is effectively relieved.
本发明公开了一种超高强全珊瑚砂海水地聚合物混凝土及其制备方法，混凝土包括质量百分比为40～45％的工业废渣，质量百分比为1～3％的碱激发剂原料，质量百分比为10％～15％的海水，质量百分比为40～45％的珊瑚砂，质量百分比为0.2%～0.5%的高性能减水剂。本发明充分利用海水、珊瑚砂等丰富的海洋资源，以碱激发剂激发矿渣、粉煤灰和硅灰形成结构致密的胶凝材料制备的超高强地聚合物混凝土，就地取材率达到45～55%，不仅减少了淡水及河沙远程运输产生的高昂代价，而且有效地缓解了淡水和河砂等自然资源的消耗，以及河砂采掘过程中对生态环境的破坏。
