Impermeable recycled concrete and preparation method thereof
According to the anti-seepage recycled concrete provided by the invention, the carbon fibers in the raw materials are subjected to surface treatment through the diphenylmethane diisocyanate and the nano silicon dioxide, so that the dispersity of the carbon fibers in the concrete preparation process is improved, and the carbon fibers are matched with the steel fibers to be used as mixed fibers; the mechanical property and the impermeability of the recycled concrete can be improved. The invention also provides a preparation method of the concrete.
本发明提供了一种抗渗再生混凝土，原料中的碳纤维通过二苯基甲烷二异氰酸酯和纳米二氧化硅对碳纤维进行表面处理，改善其在混凝土制备过程中的分散性，与钢纤维配合作为混合纤维使用，能够提高再生混凝土的力学性能和抗渗性能。本发明还提供了所述混凝土的制备方法。
