ABSTRACT Concrete is a mixture consisting of portland cement, fine aggregate, coarse aggregate and water. With increasing age, the concrete will harden and will reach the design strength (fc') at the age of 28 days. This study aims to determine the effect of diameter and specimen ratio on the compressive strength of concrete with a compressive strength value of fc' 15 MPa. Concrete compressive strength testing was carried out with cylindrical samples with a diameter of 5 cm; 7.5 cm and 15 cm with a ratio of 3;2.5;2;1.5 and 1, except for a diameter of 15cm only using the ratio 2 as the basis for the value of concrete compressive strength. The results of the average compressive strength of each diameter of the test object and compared with the results of the average compressive strength of the standard test object used in the 15cm x 30cm test which has an average compressive strength of 18.86 MPa. Comparison between cylinder 5cm x 15cm which has an average compressive strength of 23.26 MPa, cylinder 5cm x 12.5 having an average compressive strength of 24.45MPa, cylinder 5cm x 10 having an average compressive strength of 29.71 MPa, cylinder 5cm x 7.5cm average compressive strength of 33.78 MPa, cylinder 5cm x 5cm average compressive strength of 35.99 MPa, comparison with cylinder 7.5cm x 22.5cm has an average compressive strength of 17.88 MPa, cylinder 7 , 5cm x 18.75cm average compressive strength of 19.01 MPa, cylinder 7.5cm x 15 average compressive strength of 20.75 MPa, cylinder 7.5cm x 11.25cm average compressive strength of 23.77 MPa, and cylinder 7.5cm x 7.5cm average compressive strength of 30.18 MPa.
