Mix design of self-compacting concrete with limestone filler versus fly ash addition

Self-compacting concrete is nowadays the preferential choice of the construction industry, surpassing the use of ordinary concrete by reducing cast-in-place equipment and labor, while perfectly filling formwork under its own weight. However, the mix design and production processes are more prone to human errors than those for ordinary concrete and are vital for structural conformity. This paper exposes several common errors that can occur in the design and casting process and gives viable practical solutions. Furthermore, a comparison was performed between self-compacting concrete with limestone filler and self-compacting concrete with high volume fly ash added as 63% cement replacement.
