Efficient preparation method of neutral durable carbonized steel slag artificial fish reef
The invention discloses an efficient preparation method of a neutral durable carbonized steel slag artificial fish reef. The method comprises the following steps: by taking iron-removed secondary slag of steel slag as a raw material, carrying out compression molding, carbonization curing and water curing to a specified age to ensure safety, and then putting into water for use. The compressive strength meeting the application standard of the artificial fish reef can be achieved within one day after the steel slag is carbonized and cured, and the preparation efficiency of the artificial fish reef is high. Before the artificial fish reef is put into use, the artificial fish reef is maintained in water, the risk that the artificial fish reef is damaged by wind wave scouring and the like when the mechanical property is reduced to the lowest point due to microstructure changes such as mineral phase change and lattice recombination in the initial stage of water putting and use of the artificial fish reef is reduced, the stability of the mechanical property of the reef body is ensured, and the durability is better. The prepared artificial fish reef takes calcium carbonate as a main binding phase, is neutral in pH, is beneficial to attachment of organisms in water such as ocean and ponds, and is wide in application range.
本发明公开了一种中性耐久碳化钢渣人工鱼礁高效制备方法。本发明以钢渣除铁二次渣为原料，通过压制成型、碳化养护、水中养护至规定龄期确保安全后，投水使用。钢渣碳化碳化养护1天以内即可达到符合人工鱼礁应用标准的抗压强度，人工鱼礁制备效率高。人工鱼礁投入使用前，进行了水中养护，降低了人工鱼礁投水使用初期由于矿物相变、晶格重组等微观结构变化导致的力学性能降低到最低点时的风浪冲刷等对其损伤破坏的风险，确保了礁体力学性能的稳定性，耐久性更好。制备的人工鱼礁以碳酸钙作为主要结合相，pH为中性，有利于海洋、池塘等水中生物的附着，应用范围广。
