High-strength recycled concrete and preparation method thereof
The invention discloses high-strength recycled concrete in the technical field of concrete production. The high-strength recycled concrete comprises the raw materials in parts by weight: 160-180 parts of cement, 330-380 parts of coarse aggregate, 360-390 parts of recycled compound aggregate, 40-60 parts of fly ash, 2-3 parts of a water reducing agent and 20-30 parts of water. A preparation method comprises the following steps: step 1, pre-wetting the regenerated compound aggregate according to the weight parts and keeping for 5-8 hours; step 2, putting the cement, coarse aggregate and fly ash into the pre-wetted regenerated compound aggregate according to the weight parts, and uniformly mixing to obtain a mixture; and step 3, mixing water and the water reducing agent, adding the mixture into the mixture, and uniformly stirring to obtain the high-strength recycled concrete. According to the high-strength recycled concrete and the preparation method thereof, the strength of the recycled concrete can be remarkably improved.
本方案公开了混凝土生产技术领域的一种高强度的再生混凝土，包括的原料及其重量份数为：水泥160～180份、粗骨料330～380份、再生复配骨料360～390份、粉煤灰40～60份、减水剂2～3份和水20～30份。制备时包括以下步骤：步骤一、按照重量份数将再生复配骨料预湿并保持5～8h；步骤二、按照重量份数将水泥、粗骨料和粉煤灰放入到预湿后的再生复配骨料中混合均匀，得到混合物；步骤三、将水与减水剂混合，再加入到混合物中搅拌均匀得到高强度的再生混凝土。本申请中的高强度的再生混凝土及其制备方法可以显著提高再生混凝土的强度。
