摘要
试验以块体和砂浆强度为基本参数,砌筑36个蒸压粉煤灰砖砌体试件进行轴心受压试验,并配合百分表量测砌体变形。通过蒸压粉煤灰砖砌体轴心受压试验,分析了砌体受压时裂缝的发展特点和变形规律,根据36个试件的抗压试验结果,建立了蒸压粉煤灰砖砌体抗压强度的计算公式,为相关规范的编制提供试验数据,以利于蒸压粉煤灰砖的推广应用。
36 autoclaved fly ash brick masonries are built for axial compressive tests.An experiment is carried out with the strength of both masonry and mortar serving as the basic parameters and the dial indicator used for measuring the deformation of masonries.Based on the experiment,the development features of cracks and the deformation patterns of masonries under compressure are analyzed.In light of the results of axial compressive tests of all the 36 masonries,a calculative formula of the compressive strength of autoclaved fly ash brick is established,which will supply experimental data for compiling regional technical codes.And,thus,the application of autoclaved fly ash brick will be extended.
