摘　　要：通过试验指出LC30浮石混凝土早期立方体抗压强度发展较快,各组试块总均值为21.88 MPa(7 d),30.53 MPa(28 d);个别试块内部有骨料级配细化的现象,是强度不高的主要原因。利用X-R图对试件强度进行了质量分析,找出了试验中的不足,有利于进一步改进试验的措施。Pointed out by experiment LC30 the early cubic compressive strength of pumice concrete developed rapidly,the total mean value of each group of test blocks is 21.88 MPa(7 d),30.53 MPa(28 d),the phenomenon of fine aggregate gradation inside individual test blocks is the main reason for the low strength.the X-R diagram was used to analyze the quality of the test piece strength,and the deficiencies in the test were found,which is helpful to further improve the test measures.
