Water. Ordinary tap water is used. 3. Experimental SCC mix design. SCC can be made from any of the constituent materials that are normally considered for structural concrete .In designing the SCC mix, it is most useful to consider the relative proportions of the key components by volume rather than by mass .Several methods exist for the mix design of SCC.

Concrete Mix Design Introduction The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
Volume of coarse aggregate per unit volume of total aggregate is based on the grading zone of fine aggregate used to prepare the concrete mix. As the fine aggregate grading becomes progressively finer, that is from Zone 1 to 4, the ration of fine aggregate to coarse aggregate should be reduced.
