In the ACI mix design procedure, the volume of coarse aggregate is first determined based on the nominal maximum aggregate size and fineness modulus of the sand.
If the fineness modulus of the fine aggregate increases whil…
If the fineness modulus of the fine aggregate increases while keeping all other factors constant, the required coarse aggregate volume will increase according to the ACI method.
