Alkali-activated slag seawater sea sand concrete and preparation method thereof
The invention discloses alkali-activated slag, seawater and sea sand concrete and a preparation method thereof, and the concrete comprises the following components in percentage by mass: 16-20% of industrial waste residue, 1-3% of alkali activator raw material, 8-10% of seawater, 20-25% of sea sand and 45-55% of coarse aggregate, the concrete is prepared by uniformly mixing the industrial waste residues, alkali activator, seawater, sea sand and coarse aggregate. According to the prepared concrete, seawater and sea sand marine resources are fully utilized, industrial solid waste such as slag is used as a cementing material, consumption of traditional material resources such as fresh water and river sand can be reduced, and solid waste resource reutilization is achieved. The alkali-activated cementing material has the advantages of compact slurry structure, chloride ion fixation and the like, is suitable for high-temperature, high-humidity and high-salt marine environments, and can effectively reduce the construction cost and the construction period of a project when being applied to the construction of engineering infrastructures in an open sea island reef area.
本发明公开了一种碱激发矿渣海水海砂混凝土及其制备方法，混凝土包括质量百分比为16～20％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8％～10％的海水，质量百分比为20～25％的海砂，质量百分比为45～55％的粗骨料，混凝土由工业废渣、碱激发剂、海水、海砂和粗骨料均匀混合而成。本发明制备的混凝土充分利用海水、海砂海洋资源，以矿渣等工业固废物作为胶凝材料，不仅能缓减淡水和河砂等传统材料资源的消耗，还实现了固废资源再利用。碱激发胶凝材料有着浆体结构致密及固定氯离子等优点，适宜用于高温、高湿、高盐的海洋环境，其应用于远海岛礁地区工程基础设施建设，将有效地降低项目的工程造价和建造工期。
