Before we get into mix design considerations, note that you can either use a bagged mix specifically designed for concrete countertops, or mix your own from scratch. Our preference at CCI is for mixing your own, since Jeff is an engineer as well as a thrifty Yankee.
Selecting different coefficients of the water to cement ratio, the ratio of cement substituted by PFA and (over) weight coefficients of PFA, tests are carried out to study the proportion of the concrete using artificial sand mixed with PFA. On this basis, a kind of practicable proportion design method of the concrete using artificial sand mixed with PFA is proposed
