Seawater mixed fly ash geopolymer artificial fish reef and preparation method thereof
The invention discloses a seawater mixed fly ash geopolymer artificial fish reef and a preparation method thereof. The artificial fish reef comprises fly ash, mineral slag, an exciting agent, shells and Yellow Sea seawater. The preparation method comprises the steps: firstly, adding 15-50 parts of MgO and 2-5 parts of NaOH into 100-450 parts of seawater to prepare a uniformly dispersed alkali-activated solution; secondly, pouring 150-750 parts of fly ash and 50-300 parts of mineral slag into a stirring pot, and evenly pouring an alkali activator into the stirring pot to be stirred to form slurry; and when the slurry starts to thicken, adding shells to obtain fish reef concrete; and finally, pouring the fish reef concrete into a mold, curing and forming, and removing the mold. The artificial fish reef not only has higher durability and marine ecological compatibility, but also gives consideration to the early strength and the later strength of the artificial fish reef, and can resist the influence of sea tides, sea waves and ocean currents in long-term service. The marine organism adhesion capacity on the surface of the fish reef is higher, the trapping capacity of the artificial fish reef on various fish schools is remarkably improved, fresh water resources are saved while the production cost is reduced, and the problem of recycling of industrial waste is solved.
一种海水拌合粉煤灰地质聚合物人工鱼礁及其制备方法，包括粉煤灰、矿渣、激发剂、贝壳和黄海海水。制备方法为：首先，将15‑50份的MgO和2～5份的NaOH加入100～450份的海水中，制得分散均匀的碱激发溶液。其次，将150～750份粉煤灰和50～300份矿渣倒入搅拌锅中，将碱激发剂均匀倒入搅拌锅内搅拌后成浆体。当浆体开始增稠时加入贝壳，得到鱼礁混凝土。最后将其倒入模具中，养护成型后拆模。本发明不仅有更高的耐久性和海洋生态相容性，同时兼顾人工鱼礁的早期强度和后期强度，能在长期服役中抵御海潮、海浪、海流的影响。鱼礁表面海洋生物附着能力更强，人工鱼礁对各类鱼群的诱集能力显著提高，并且在降低生产成本的同时节约淡水资源，解决工业废弃物的再生利用问题。
