CONCRETE FORMULAS 149 a 28day compressive strength of 6000 lb/in2 (41 MPa) and for 2000 lb/in2 (14 MPa). Airentrained concrete w/c ratios vary from to for 5000 lb/in2 (34 MPa) and 2000 lb/in2 (14 MPa) compressive strength, respectively. Be certain to refer to the ACI Code for the appropriate w/c value when preparing designs or concrete analyses.
