High-performance concrete prepared from recycled slurry water
The invention discloses high-performance concrete prepared from recycled slurry water, and relates to the field of concrete, and the high-performance concrete comprises the following components by weight: 120-260 parts of cement; 510 to 560 parts of broken stone; 335 to 425 parts of machine-made sand; 120 to 180 parts of fly ash; 90 to 110 parts of glass ultrafine powder; 130 to 220 parts of tailing ultrafine powder; 80 to 100 parts of steel fiber; 90 to 120 parts of starch solution; 40 to 60 parts of nano silicon dioxide; 20 to 30 parts of sodium carboxymethyl cellulose; the fly ash, the glass superfine powder, the nano silicon dioxide and the sodium carboxymethyl cellulose are adopted as filling materials, and the sodium carboxymethyl cellulose generates certain viscosity after being dissolved in water, so that a three-dimensional structure is formed in an alkaline environment; the fly ash, the glass ultrafine powder and the silicon dioxide can be bonded on the surface of the aggregate, the porosity of the coarse concrete is reduced, the structure of the recycled concrete is more compact, the impermeability of the recycled concrete is improved, and the structural strength of the recycled concrete is improved.
本发明公开了一种利用回收浆水制备的高性能混凝土，涉及混凝土领域，本发明包括如下的重量份数的组分：水泥120‑260份；碎石510‑560份；机制砂335‑425份；粉煤灰120‑180份；玻璃超细粉90‑110份；尾矿超细粉130‑220份；钢纤维80‑100份；浆水90‑120份；纳米二氧化硅40‑60份；羧甲基纤维素钠20‑30份；外加剂20‑28份，本发明通过采用粉煤灰、玻璃超细粉、纳米二氧化硅和羧甲基纤维素钠，粉煤灰、玻璃超细粉和二氧化硅为填补料，而羧甲基纤维素钠溶于水后产生一定的粘性，在碱性环境中形成三维结构，进而可将粉煤灰、玻璃超细粉和二氧化硅粘结在集料表面，降低粗混凝土的孔隙率，使再生混凝土的结构更加致密，从而改善再生混凝土的抗渗性能，有利于提升再生混凝土的结构强度。
