Preparation method of foam concrete for artificial fish reef
The invention discloses a preparation method of foam concrete for an artificial fish reef, and belongs to the technical field of artificial fish reef preparation. The foam concrete for the artificial fish reef comprises modified rice straw fibers, scallop shell particles, fly ash, cement, water, a foaming agent and a composite additive. The composite additive comprises a polycarboxylic acid water reducer and a fatty alcohol polyoxyethylene ether sodium sulfate foam stabilizer. The preparation method of the foam concrete for the artificial fish reef comprises the following steps: mixing the ordinary Portland cement and the fly ash, and grinding to obtain a dry-base gelling component; adding water which is 0.3-0.5 time of the total mass of the dry-based gelling component and the dry-based gelling component into a stirrer, and uniformly stirring; adding the scallop shell particles and the modified rice straw fibers in parts by mass, and uniformly stirring; and finally, adding the foaming agent and the composite admixture in parts by mass, mixing, stirring, putting into a mold, molding, and naturally curing for 28 days to prepare the foam concrete for the artificial fish reef. The foam concrete is adopted, so that the alkalinity of the concrete is reduced, and the adhesiveness of marine organisms is improved; the scallop shells and the rice straws are added, so that the resource utilization of biomass is realized, and the carbon sequestration capability and the impact resistance of the artificial fish reef are also enhanced.
本发明公开了一种人工鱼礁用泡沫混凝土的制备方法，属于人工鱼礁制备技术领域。人工鱼礁用泡沫混凝土包括改性水稻秸秆纤维、扇贝壳颗粒、粉煤灰、水泥、水、发泡剂、复合外加剂。复合外加剂包括聚羧酸减水剂和脂肪醇聚氧乙烯醚硫酸钠稳泡剂。人工鱼礁用泡沫混凝土制备方法为：将普通硅酸盐水泥、粉煤灰混合磨制干基胶凝组分；将干基胶凝组分总质量0.3～0.5倍的水和干基胶凝组分加入搅拌机，搅拌均匀；按质量份加入扇贝壳颗粒和改性水稻秸秆纤维，搅拌均匀；最后按质量份加入发泡剂和复合外加剂，混合搅拌，入模、成型、自然养护28d，制得人工鱼礁用泡沫混凝土。本发明采用泡沫混凝土，降低了混凝土碱度，提高了海洋生物附着性；添加扇贝壳和水稻秸秆，不仅实现了生物质的资源化利用，还增强了人工鱼礁的碳封存能力和抗冲击性。
