摘　　要：试验利用建筑垃圾骨料、水泥、粉煤灰等原材料制备建筑垃圾混凝土砌筑用砖,探究了粉煤灰掺量、粉煤灰激发剂掺量对建筑垃圾混凝土砌筑用砖性能的影响,并对粉煤灰激发剂的影响机理进行了初步探究。在满足GB/T21144-2007《混凝土实心砖》要求下,粉煤灰掺量≤20%,粉煤灰激发剂的最佳掺量为1.0%。This experiment uses construction waste aggregate, cement, fly ash and other raw materials to prepare concrete masonry brick, then investigates the influence of the content of fly ash and the amount of fly ash activator on the performance of the concrete masonry brick, and discusses the mechanism of fly ash activator. Under the requirements of GB/T21144-2007 "Concrete solid brick", the content of fly ash is less than 20%, and the optimum dosage of fly ash is 1.0%.
