Even though the aggregate has a 5% absorption rate, the concrete will have a watercement ratio of to —made possible with the addition of waterreducing admixtures. Test cylinders taken from trial batches broke at 6000 psi—the same as cylinders made with allquarried aggregate.
Because cement is the most expensive ingredient in making concrete, it is desirable to minimize the amount of cement used. 70 to 80% of the volume of concrete is aggregate in order to keep the cost of the concrete low.
