Tailing aggregate foam concrete and preparation method thereof
The invention discloses tailing aggregate foam concrete and a preparation method thereof. The tailing aggregate foam concrete is prepared from the following raw materials: cement, tailing sand, a water reducing agent, water, a supported catalyst, a density regulator and a deactivator. Wherein the supported catalyst is prepared by supporting lipidated and coated iron-nickel alloy catalyst powder with silica fume. And the density regulator adopts hydrazine borane. A color fixing agent NFC is adopted as the deactivating agent. The preparation method of the tailing aggregate foam concrete comprises the following steps: firstly, uniformly stirring and mixing the cement, the gold tailing sand and the supported catalyst in a stirrer to obtain a dry material A; mixing a water reducing agent, a density regulator and 80% of water to obtain a solution B; mixing a color fixing agent with the remaining 20% of water to obtain a solution C; stirring and mixing the dry material A and the solution B, adding the solution C, and uniformly stirring and mixing to obtain concrete slurry; and finally, pouring and molding the mixed concrete slurry in a mold, standing for foaming, and curing to obtain a foam concrete finished product. The tailing foam concrete has the characteristics of light weight and high strength.
本发明公开了一种尾矿集料泡沫混凝土及其制备方法。该尾矿集料泡沫混凝土的原料由水泥、尾矿砂、减水剂、水、负载催化剂、密度调节剂和去活剂组成。其中负载催化剂是以硅灰负载脂化包覆的铁镍合金催化剂粉制成。密度调节剂采用肼硼烷。去活剂采用固色剂NFC。该尾矿集料泡沫混凝土制备中，首先将水泥、金尾矿砂和负载催化剂在搅拌机中搅拌混合均匀，得到干物料A；将减水剂、密度调节剂和80％的水混合，得到溶液B；将固色剂和剩余的20％水混合，得到溶液C；然后将干物料A与溶液B搅拌混合，再加入溶液C，搅拌混合均匀，得到混凝土浆体；最后将混合后混凝土浆体在模具中灌注成型，静置待其发泡，再经过养护，得到泡沫混凝土成品。该尾矿泡沫混凝土具有轻质高强的特点。
