摘　　要：为了建立不同龄期蒸压粉煤灰砖砌体抗压强度的计算式,按照砌体基本力学性能标准试验方法,对不同龄期的蒸压粉煤灰砖砌体及其专用砂浆进行了抗压试验,找出不同龄期专用砂浆强度的变化规律,建立了不同龄期蒸压粉煤灰砖砌体抗压强度的计算式,计算出的数值与试验值比较精确度达到了98%左右,可以作为工程研究的依据。In order to deduce the formula for calculating the compressive strength of the different age autoclaved fly ash brick masonry, an experiment on the compressive of different age autoclaved fly ash brick masonry and of the special mortar is tarried out by properties. The formula is deduced for calculating strength vary of special mortar in different ages. 98 can provide the basis of engineer research. the standard test method of the basic masonry mechanical different age is fly ash brick masonry on the basis of the % of calculated values accord with the test values, which
