摘　　要：通过6个新型自保温混凝土砌块砌体试件的弹性模量试验,对自保温混凝土砌块砌体受压应力-应变曲线的特点进行了较为细致的分析;提出了自保温混凝土砌块砌体弹性模量的建议计算公式,可为自保温混凝土砌块的工程设计及应用提供参考;将弹性模量的试验结果与公式计算值、规范值进行深入的比较分析,从而得到弹性模量的试验数据是收敛的、可靠的。同时,由于自保温混凝土砌块砌体的弹性模量试验值大于同条件下混凝土空心砌块砌体的弹性模量,说明该自保温混凝土砌块有较好的抗变形能力,可替代同条件下普通混凝土空心砌块。Through the elastic modulus experiments of six compression specimens of new composite thermal insulation concrete block masonry,the law of stress-strain curve has been carefully analyzed in this paper. The calculating formula of the elastic modulus of composite thermal insulation concrete block masonry is proposed to provide a reference for engineering design and application of this new wall material. In addition,the test results are compared with the calculated formula values and the norms values. And it＇s obvious that the elastic modulus of composite thermal insulation concrete block masonry is greater than that of ordinary concrete hollow block. It reveals that the former has better ability to resist deformation,and can be used to replace the normal ones under the same conditions.
