Mukul Kumar Singh says:

Sir Practicaly it is not possible to make wokable concrete 138 lt/m3 with 1.6 kg/m3 admixture, because I am facing problem at site even puting 180 lt/m3 with 0.8% admixture also for M25 grade of concrete.

N.vinoth kannan says:

Dear sir
thanks you for your mix design please sent to the c sand+r sand combination with m25,m30 mix
