High strength concrete properties, admixture, and mix ...

Till the late 1970s, the use of concrete in excess of M40 in tall buildings was not known. Now, with the effective use of admixtures and other sophisticated applications of concrete technology, it is easy to achieve a strength of 50 MPa in 12 to 18 hours, and above 70 MPa at 28-days.. It is feasible to produce concrete having a compressive strength of up to 150 MPa at 91-days.
