This paper addresses mainly workability of dry-mixed self-compacting concrete (DSCC) based on the experimental study. Ten mix proportions for DSCC are designed by the orthogonal test method with fixed fine and additive content when coarse aggregate content and water content are used as variables. The workability (including filling ability, passing ability and segregation resistance) of fresh DSCC is quantitatively evaluated by slump flow, L-box, U-box and circular steel column of stability tests. It is found that DSCC of 13% water content has better fluidity, deformability and filling ability than DSCC of 12% water content and better uniform aggregate distribution and segregation resistance than DSCC of 14% water content based on the experimental results. It can be concluded that DSCC of 13% water content presented in this paper satisfy various requirements for workability and can be used for the design of practical concrete structures.
