This research aims to determine the effect of maximum grain size on high quality concrete compressivestrength (F'C 40 MPa) and the benefits of this study, to produce high quality economical concrete. Large aggregateusage requires less cement than the smaller maximum grain size. This research uses 40 MPa quality concrete, todetermine the effect of maximum grain size on the quality of concrete is done by making the cylinders 15 pieces eachfor maximum grain size 10 mm, maximum grain size 20 mm and maximum size 40 mm, for all variations using thesame weight of cement. The result showed that the strength of the maximum 10 mm size was obtained by 37 MPa, themaximum size of 20 mm was obtained 41 MPa, and the maximum size of 40 mm was obtained 49 MPa, it showed thatthe largerof the aggregate size, the compressive strength is increasing forthe same amount of cement.
