adding HVFA and SF together to create a ternary mix of SCC, the cement was first altered separately to create binary bland. In binary blend, either FA (40-80%) or SF (2-10%) has been incorporated in the place of OPC with various percentage and in ternary blend SF (8%) has been incorporated with FA (40-80%) as a replacement of OPC. 2.2% of superplasticizer with built-in VMA was required to achieve the required workability. The mix proportion of materials needed to make one cubic meter of SCC is shown in Table 1.
