摘　　要：按照《砌墙砖试验方法》(GB/T2542-2003)对蒸压粉煤灰砖进行砖的含水率、抗压强度、抗折强度试验。确定蒸压粉煤灰砖的基本力学指标,为编制辽宁省地方标准《蒸压粉煤灰砖建筑技术规范》提供试验依据。结果表明,蒸压粉煤灰砖含水率为2.96%,抗压强度为11.46MPa,抗折强度为1.68MPa,在实际工程上可替代普通烧结砖使用。According to the GB/T 2542-2003 of masonry brick test method,the moisture content,compressive strength,transverse strength of the autoclaved fly ash brick are test.The results show that the autoclaved fly ash brick moisture content is 2.96 %,the compressive strength is 11.46 MPa,and the transverse strength is 1.68 MPa,so it can used as a substitute for the common fired brick in project.The mechanics index can provide a basis for the Liaoning standards of fly ash brick construction technical specifications.
