High-strength recycled concrete and preparation method thereof
The invention discloses high-strength recycled concrete and a preparation method thereof, and the preparation method comprises the following steps: (1) uniformly mixing natural fine aggregate, recycled coarse aggregate and stainless steel fiber to obtain a first mixture; (2) uniformly mixing Portland cement, fly ash, silica fume and an adhesive to obtain a second mixture; (3) uniformly mixing a polycarboxylate superplasticizer, sodium gluconate, carbon nanofibers and water to obtain a third mixture; and (4) sequentially adding the first mixture and the second mixture into the third mixture, and uniformly mixing to obtain the recycled concrete. According to the high-strength recycled concrete and the preparation method thereof, the recycled concrete can have relatively high compression resistance, impact resistance and wear resistance, and the raw materials of the recycled concrete can have high elastic modulus, high bending resistance and high tensile strength.
本发明公开了一种高强度再生混凝土及其制备方法，包括以下步骤：步骤(一)：将天然细骨料、再生粗骨料和不锈钢纤维混合均匀，得到第一混合物；步骤(二)：将硅酸盐水泥、粉煤灰、微硅粉和胶粘剂混合均匀，得到第二混合物；步骤(三)：将聚羧酸减水剂、葡萄糖酸钠、纳米碳纤维和水混合均匀，得到第三混合物；步骤(四)：将第一混合物和第二混合物依次加入第三混合物中，混合均匀，得到再生混凝土。该高强度再生混凝土及其制备方法，能够使该再生混凝土具有较强的抗压性能，抗冲击和耐磨性能，且可使再生混凝土的原料具有高弹性模量、高抗弯和抗拉强。
