Study on Application of Machine-made Sand Self compacting Concrete in Tunnel Secondary Lining
An environmentally friendly self-compacting concrete for tunnel lining was prepared by replacing river sand with mechanism sand, adding appropriate amounts of stone powder and fly ash to adjust the workability and reduce cement consumption. After studying the effects of different coarse aggregate gradations, sand ratios, stone powder contents, and fly ash contents on the workability of the self-compacting concrete, the optimal mix proportion was determined. The best results were obtained when the coarse fine aggregate proportion was 6:4, the sand ratio was 0.43, the stone powder content was 5%, the fly ash content was 25%, and the water-cement ratio was 0.32, which met the engineering strength requirements. This provides a theoretical basis for the application of mechanism sand self-compacting concrete in tunnel secondary lining works.
