Magnesium oxide excited slag geopolymer artificial fish reef and preparation method thereof
The invention belongs to the field of comprehensive utilization of solid waste resources, and provides a magnesium oxide excited slag geopolymer artificial fish reef and a preparation method thereof. Raw materials of the artificial fish reef are as follows: 120-190 parts of slag, 80 to 120 parts of shells; 20 to 40 parts of gypsum; 10 to 20 parts of magnesium oxide; 2-5 parts of a water reducing agent; 1-2 parts of a defoaming agent; 1-2 parts of sodium hydroxide; and 50-70 parts of mixing water. The preparation method comprises the following steps: firstly, adding the defoaming agent, the sodium hydroxide and the water reducing agent into the mixing water, and stirring for 3 minutes to form a uniform mixing solution; secondly, adding the slag, magnesium oxide, gypsum and shells into a stirring pot, uniformly stirring, then adding the stirring solution, uniformly stirring, and pouring the prepared slurry into a mold; and finally, maintaining the sample in an air environment, and removing the mold. The magnesium oxide excited slag geopolymer artificial fish reef prepared by the invention not only has lower production cost, but also has better strength and durability, meanwhile, the pH value of the dissolution liquid is low, and the artificial fish reef has better marine ecological performance, is beneficial to promoting comprehensive utilization of industrial source solid waste resource slag and coast source solid waste resource shell, and has remarkable environmental protection, economic and engineering application values.
本发明属于固废资源综合利用领域，提供一种氧化镁激发矿渣地聚物人工鱼礁及制备方法，其原材料为：矿渣120‑190份；贝壳80‑120份；石膏20‑40份；氧化镁10‑20份；减水剂2‑5份；消泡剂1‑2份；氢氧化钠1‑2份；拌合水50‑70份。制备方法为：首先，将消泡剂、氢氧化钠、减水剂加入拌合水中，搅拌3min，形成均匀的拌合溶液；其次，将矿渣、氧化镁、石膏、贝壳加入至搅拌锅中搅拌均匀，再加入拌合溶液搅拌均匀，将制备的浆体浇注于模具中；最后，将试样在空气环境中养护后拆模。本发明制备的氧化镁激发矿渣地聚物人工鱼礁不仅具有较低的生产成本，还有较好的强度、耐久性，同时溶出液pH值低，具备较好的海洋生态性能，有利于推动工业源固废资源矿渣、海岸源固废资源贝壳的综合利用，具有显著的环保、经济及工程应用价值。
