| Abstract: | Through experiment and research,the compatibility of polycarboxylate admixtures with cements is verified and the application of C20 self-compacting concrete in the basis of bridge abutment is presented.With production of self-compacting concrete under strict control,and the performance checked before cast,self-compacting concrete mould is randomly chosen to analyze the compression index.Results show the compression strength of self-compacting concrete reaches the strength level of C20. |
