Feb 22, 2016 · This high strength concrete mix design has been developed by B. W. Shacklock and H. C. Erntroy in 1954. For designing concrete mix of low and medium grade compressive strength i.e. up to 35 MPa, it is assumed the strength of fully compacted concrete at a required age to be dependent only on the w/c ratio of the mix.
