摘　　要：文中针对目前塑性混凝土由于自身较低的弹性模量,采用常规普通混凝土测试方法得出的结果往往偏高的问题,对弹性模量的测试方法进行了改进。试验结果表明,改进后测试标距为190 mm时测得的弹性模量小于普通混凝土标准方法测得的值,在工程应用过程中更加贴近实际结构的弹性模量;通过优化胶凝材料、膨润土和骨料三者的用量,可以制备出抗压强度10 MPa,弹性模量1.5 GPa的塑性混凝土。This article aims at the current plastic concrete due to its low elastic modulus,, and the results obtained by using conventional ordinary concrete test methods are often high. The test results show that the modulus of elasticity measured when the modified test gauge is 190 mm is less than the value measured by the standard method of ordinary concrete, In the process of engineering application, it is closer to the elastic modulus of the actual structure;It can be used to prepare plastic concrete with compressive strength of 10 MPa and elastic modulus of 1.5 GPa.
