| Abstract: | Based on the initial self-compacting concrete mix,the main impacting factors such as the content of fly ash,the sand ratio,and the amount of thickener and superplasticizer are analyzed on the performance of self-compacting concrete with local raw materials through orthogonal test,and C30 core-column self-compacting concrete which meet the requirements of self-compacting performance and strength is optimized,and with Cb30 grout concrete is economically analyzed. |

| Keywords: | core-column self-compacting concrete orthogonal test optimization |
