Large-scale efforts are needed for conservation of natural sand whose resources are reducing day by day and legal complications are making it difficult to meet the demand. So, self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The hardened concrete is dense, homogeneous and has the same engineering properties and durability as traditional vibrated concrete. Complex shape of concrete structures and densely arranged bars make it more difficult to use a vibrator. Vibratory compaction is noisy and deleterious to the health of construction workers, as well as an annoyance to people in the neighborhood. In remote areas it is difficult to find skilled workers to carry out the compacting work at construction sites. This paper presents the progress of the research on different harden properties of Self Compacting Concrete using the Ordinary Portland Cement “Ultratek” made and low-calcium fly ash from Birla Glass, Kosamba, Gujarat, as binder materials in making the concrete mixes along with other ingredients locally available. Results indicated increase in workability for all the cases over control concrete. Concrete with fly ash was also found to be about 25% economical when cost per N/mm2 was compared. Based on experimental results correlations are developed to predict Compressive Strength, Flexural strength, cost, Slump and Dry Density for percentage sand replacement with fly ash.
