One of the best concrete mix ratios is 1 part cement, 3 parts sand, and 3 parts aggregate, this will produce approximately a 3000 psi concrete mix The strength of this mix ratio is good for most concrete slabs, footings, steps, and foundation wallsTECHNICAL NOTES 8 GRINDING R P King, 8-3 Centrifugal force outward Fc mp& 2 Dm 2 (81) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners Gravitational force Fg mpg (82) The particle will remain against the wall if these two forces are in balance ieConcrete Driveway Construction, Thickness is the major factor (even more than the strength of the concrete) in determining a driveway's structural capacity Place concrete at a minimum thickness of 4 inches Increasing the thickness from 4 inches to 5 inches will add approximately 20% to your concrete cost, but will also boost your driveway's load-carrying capacity nearly 50 ,.
