# testing of concrete for compressive strength and qua

### high early strength of self-consolidating concrete incorporating qua ...

The workability test and compressive strength test were conducted to determine properties of fresh and hardened conventional concrete and SCC. The early strength of conventional and SCC concrete cubes were tested after 24 hours of casting. As expected, the innovation material incorporating Qua-Si-RHA in SCC...
