These are actual concrete mix ratios for 3000, 3500, 4000, and 4500 psi concrete. Updated November 3, 2023. Author: Michael Day. These concrete mix ratios for 3000, 3500, 4000, and 4500 psi concrete come from the ready mix concrete company I use to pour concrete floors, slabs, patios, pool decks, and stamped concrete.
The target strength formula is done as follows: ftarget = fck + 1.65 x S, Where S is= the standard deviation in N/mm2. The advantages of concrete mix design are that it gives the proper quantities of components, making concrete construction inexpensive in terms of reaching the requisite strength of structural parts.
