摘要: 利用包头地区电厂粉煤灰、少量水泥、河砂,在碱性复合激发剂存在的情况下通过湿热养护工艺制成承重标准砖。试验采用单因素试验设计,得到粉煤灰掺量58.3%的粉煤灰砖,湿热养护28 d抗压强度18.7 MPa,抗折强度3.4 MPa。对影响砖体强度的几个主要因素进行了分析。

关键词: 粉煤灰, 碱激发, 蒸养, 抗压强度, 抗折强度

Abstract: The load-bearing standard brick was prepared by coal ash from a power plant of Baotou by wet thermo-curing method under alkaline compound activator,with addition of small quantity of cement and river sand.Through the single-factor experiments,the bricks with fly ash contents of up to 58.3% were obtained and its compressive strength of the brick reached 18.7 MPa,and bending strength 3.4 MPa at thermo-curing of 28 d.Then,some factors influencing the hardness of the brick were analyzed.

Key words: Coal ash, Alkali-activated, Steam curing, Compression strength, Breaking strength
