摘要
研究了利用建筑垃圾再生微粉作矿物掺合料所配制的混凝土的各项性能。研究结果表明,建筑垃圾再生砂粉有一定的活性,其各项性能指标满足Ⅱ级粉煤灰要求,可作为混凝土矿物掺合料使用。利用建筑垃圾再生微粉配制的C30、C50混凝土,掺量在20%以下时,对混凝土各项性能影响不大,配制出的再生混凝土工作性能和耐久性能与基准混凝土相当。
The properties of the concrete made from the construction waste recycled powder were studied. The results showed that, the construction waste recycled powder has certain activity, all its performance meet the requirements of grade Ⅱ fly ash, it can be used as mineral admixtures. When the dosage is below 20%, the performance of the C20, C50 concrete that made from the construction waste recycled powder have no change and its durability is almost the same as the reference concrete.
