Cementing material for offshore photovoltaic power generation non-autoclaved curing PHC pipe pile concrete
The invention relates to the technical field of cementing materials, in particular to a cementing material for offshore photovoltaic power generation non-autoclaved curing PHC (prestressed high-strength concrete) pipe pile concrete, which comprises the following raw materials in percentage by mass: 60 to 80 percent of Portland cement clinker, 10 to 30 percent of fly ash, 5 to 15 percent of silica fume and 5 to 10 percent of sulphoaluminate cement, comprising the following raw materials in percentage by mass: 0.1-0.2 wt.% of a defoaming agent, 0.1-0.15 wt.% of a retarder and 1-2 wt.% of an early strength agent. The grading of the cementing material is optimized, and the mechanical property of the cementing material is improved on the basis of not increasing the cost of the raw materials.
本发明涉及胶凝材料技术领域，具体涉及一种海上光伏发电免蒸压养护PHC管桩混凝土用胶凝材料，所述胶凝材料包括按质量百分数计的以下原料：60wt.％～80wt.％硅酸盐水泥熟料、10wt.％～30wt.％粉煤灰、5wt.％～15wt.％硅灰、5wt.％～10wt.％硫铝酸盐水泥，包括以上原料总质量百分数计的外加剂：0.1wt.％～0.2wt.％消泡剂、0.1wt.％～0.15wt.％缓凝剂、1wt.％～2wt.％早强剂。本发明优化胶凝材料的级配，实现在不增加原料成本的基础上，提高胶凝材料的力学性能。
