摘要 通过对矩形和圆形孔2组轻质烧结页岩砖砌体抗压试件(每组6件)进行抗压强度试验,对比研究了这2种砖砌体抗压强度及弹性模量。结果表明:当所用水泥砂浆强度等级相同时,相同孔洞率的圆形孔砖砌体的抗压强度大于矩形孔砖砌体,且二者抗压强度值皆大于GB 50003—2011规定的理论计算值,并有一定的安全储备;圆形孔砖砌体的弹性模量略大于矩形孔砖砌体的弹性模量;2种孔型轻质烧结页岩砖砌体的延性要优于普通页岩多孔砖砌体。 By the compression test of two groups of compressive specimens of light-weight shale sintered brick masonry with rectangular hole and circular hole (every group has 6 pieces) to have a comparative study on compressive strength and elastic modulus of these two kinds of light-weight shale sintered brick masonry. The result shows the following conclusions: under the cir- cumstance of using same strength grade of cement mortar, the compressive specimens of brick masonry with circular hole is greater than the rectangular hole's which the hole ratio is same as the circular hole's. The measured value of compressive specimens of these two pieces of brick masonry is greater than the demand of Code for Design of Masonry Structures GB 50003-2011,and also has a certain safe stock. The elastic modulus circular hole's is slightly greater than rectangular hole's. These two kinds of brick masonry have stronger ductility than the ordinary shale sintered brick masonry.
