Study on mechanical property of high-strength concrete block masonry

Meng Fanxiao

Abstract

Experimental study is made on properties of 22 compression specimens and 9 shear specimens of high-strength concrete block masonry with mortar strength less then Mb10.Failure features,compression strength,elastic modulus and Poisson ratio of the masonry under different affecting factors are analyzed,and compared them with GB 50003-2001《Design Code of Masonry Structure》 and with formulas in correlated references.Suggestion formulas of calculating mechanical performance index of high-strength concrete block masonry are presented and the calculation result is in accord with the experimental value.
