Design a concrete mix for construction of an elevated water tank. F high strength concrete mix design g mix design based on flexural strength h road note no.
For new construction or repairs where concrete thickness exceeds 2 inches you ll want to count on a preblended mixture that can. Now what is mix design. For a given type of cement and aggregates used the reference number corresponding to the design strength at a particular age is interpolated from figure 1 to 4. Hence it is intended for use by engineers familiar with the design of concrete structures using particularly cp65 but who have little or no experience of high strength concrete hsc.
