(鄭州大學土木工程學院，鄭州 450002)［摘要］通過對不同強度等級砂漿砌筑的表面帶凸凹槽蒸壓粉煤灰磚砌體的受剪和受壓性能試驗，對其抗剪和抗壓強度進行了分析。結果表明，表面帶凸凹槽蒸壓粉煤灰磚砌體的抗剪和抗壓強度均不低于粘土磚砌體相應的強度，在抗震設計中可按粘土磚房的相應規(guī)定執(zhí)行，擴大了蒸壓粉煤灰磚在地震區(qū)的應用范圍。［關鍵詞］蒸壓粉煤灰磚；砂漿強度；抗剪強度；抗壓強度Experimental study on mechanical property of masonry made of autoclaved flyash-lime bricks with concave and convex surfaceLiu Lixin, Tian Gaoyan, Cai Xiulan(School of Civil Engineering, Zhengzhou University, Zhengzhou 450002，China)Abstract:Based on the test results of the masonry made of autoclaved flyashlime bricks with the concave and convex surface under shear and compression, the shear strength and compressive strength of the brick masonry are analyzed and discussed. The results show that both the shear strength and the compressive strength of the masonry made of autoclaved flyashlime bricks with the concave and convex surface are not less than those of fire clay brick masonry with the same brick strength and mortar strength, and these autoclaved flyashlime bricks can be used as the same as the fire clay bricks in buildings in the earthquake zone by the stipulations of the Code for seismic design of buildings of China.Keywords:autoclaved flyashlime brick；mortar strength；shear strength；compressive strength河南省新型墻材料專項基金項目(豫建墻2007-21)。作者簡介：劉立新，碩士，教授，Email:liuli-xin@126.com。參考文獻［1］GB50011—2001建筑抗震設計規(guī)范［S］.北京：中國建筑工業(yè)出版社，2001.［2］GB50003—2001砌體結構設計規(guī)范［S］.北京：中國建筑工業(yè)出版社，2001.［3］GBJ129—90砌體基本力學性能試驗方法標準［S］.北京：中國建筑工業(yè)出版社，1990.
