Evaluation of Mechanical Properties at early Ages of Dry-Mixed Self-Compacting Concrete
This paper evaluates mainly the dry-mixed self-compacting concrete (DSCC) based on the experimental study. The study analyzes mechanical properties of DSCC at the hardened condition, which has been conducted as follows: compressive strength and split tensile strength with elapsed age as well as size effect of strength. Rate of gain in strength at different periods of curing such as 1day, 3days, 7days, 14days and 28days are studied for different DSCC mixes and suitable relations have been established for the gain in strength at the early ages. Relations have also been formulated for compressive strength and split tensile strength for DSCC mixes. Size effect of compressive strength and structural efficiency have been evaluated, all at cured after 28 days.
