Aimed at the problem of low utilization rate of stone chips, stone chips wet shotcrete was prepared. The effects of replacement amount of stone chips (replacement of manufactured sand by stone chips), sand ratio and fly ash content on the workability, chloride penetration resistance, sulfate corrosion resistance and pore structure of wet shotcrete were studied. The results show that the mechanical properties and durability of concrete can be improved by the appropriate replacement amount of stone chips, but the greater the replacement amount of stone chips is, the more obvious the decline in the workability of concrete is. Compared with manufactured sand shotcrete, stone chips wet shotcrete has good mechanical properties. On this basis, the proper sand ratio and fly ash content can further improve the workability and durability of stone chips wet shotcrete. When the sand ratio of shotcrete is 55% and the fly ash content is 20% (mass fraction), the comprehensive performance of stone chips wet shotcrete reaches the best, which has reference significance for the application of stone chips in wet shotcrete.
