粉煤灰砌筑干粉在砌体结构中的应用试验研究

Study on the Fly-ash Mortar in Masonry Structure

对粉煤灰砌筑干粉砌体进行轴心抗压试验,并将其与粉煤灰砖普通水泥砂浆砌体从裂缝发展特点和变形规律、抗压强度、应力—应变曲线、弹性模量和泊松比等方面进行比较分析,研究粉煤灰砌筑干粉在砌体结构中的应用。结果表明,粉煤灰砌筑干粉能够替代普通水泥砂浆,为粉煤灰砌筑干粉推广应用提供了理论依据。

Based on compressive test of fly-ash brick and fly-ash mortar masonry,the author analyzed and compared the fly-ash brick and fly-ash mortar masonry with the fly-ash brick and normal mortar masonry on the developing feature of crack adn transfiguration law,the compressive strength,stress-strain curves, elastic module and poisson ration,and so on. The results showed that fly--ash mortar could be used to replace normal morter and they also provided the basis in theory for further popularizing and applying fly--ash mortar.
