为研究乌鲁木齐地区C30自密实混凝土力学性能，采用乌鲁木齐地区常用原材料配制C30自密实混凝土和普通混凝土，对配制出的混凝土进行立方体抗压强度、棱柱体抗压强度、劈裂抗拉强度和受压应力-应变曲线试验，对自密实混凝土和普通混凝土的试验结果进行对比分析。试验结果表明：自密实混凝土的立方体抗压强度、棱柱体抗压强度、劈裂抗拉强度高于普通混凝土，且自密实混凝土后期承载力显著提高；自密实混凝土横向应变、纵向应变及泊松比随应力水平的发展趋势与普通混凝土相同；自密实混凝土峰值应变略低于普通混凝土。

To study the mechanical performance of C30 self-compacting concrete in Urumqi area,preparation of C30 self-compacting concrete using common raw materials of Urumqi,on the preparation of the concrete cube compressive strength,prism compressive strength, splitting tensile strength and compressive stress-strain curve test.The test results showed that self compacting concrete cube compressive strength,prism compressive strength,splitting tensile strength were higher than ordinary concrete,the later bearing capacity of self compacting concrete increased significantly;self compacting concrete longitudinal strain and lateral strain,poisson's ratio with the development trend of stress levels as the same as ordinary concrete;self compacting concrete peak strain was slightly lower than that of ordinary concrete.
