Environment-friendly recycled concrete and preparation method thereof
The invention discloses environment-friendly recycled concrete and a preparation method thereof. The environment-friendly recycled concrete is prepared from the following components: recycled coarse aggregate, natural coarse aggregate, cement, fly ash, natural sand, a water reducing agent and hydrotalcite-like compound, the hydrotalcite-like compound is a double metal hydroxide; the double-metal hydroxide is selected from any one of magnesium-aluminum hydroxide, zinc-aluminum hydroxide and magnesium-chromium hydroxide. The environment-friendly recycled concrete provided by the invention is prepared from recycled aggregate, waste concrete can be consumed, and stacking of construction waste is reduced; the recycled concrete is also added with fly ash for filling gaps among aggregates, so that the mechanical strength of the recycled concrete is enhanced through grain composition, the exploitation and consumption of resources are reduced, industrial waste residues are turned into wealth, and the sustainable development of the resource environment is facilitated.
本发明公开了一种环保再生混凝土和制备方法，所述环保再生混凝土包括以下组分：再生粗骨料、天然粗骨料、水泥、粉煤灰、天然砂、减水剂和类水滑石；所述类水滑石为双金属氢氧化物；所述双金属氢氧化物选自镁铝氢氧化物、锌铝氢氧化物和镁铬氢氧化物中的任意一种。本发明提供的环保再生混凝土是利用再生骨料制备得到，能够消耗废弃混凝土，减少建筑垃圾的堆放；该再生混凝土还添加了粉煤灰，用于填充骨料间的空隙，通过颗粒级配增强了再生混凝土的力学强度，也减少了资源的开采和消耗，将工业废渣变废为宝，有利于资源环境的可持续发展。
