Abstract

ABSTRACK This research discusses the analysis of the effect of the added cbm cement additive with increasing dosage on the compressive strength of K-300 concrete. In this study, a cbm cement additive was used, namely a high quality cement mixture, a premium concentrated cement mixture specifically designed to improve the quality and strength of a building This study used a cube-shaped sample (15cm x 15cm x 15cm), the quality of which was planned was 300 kg / cm2. Samples were tested at 3, 7, and 28 days of age, with treatment prior to testing. The total number of samples was 54 samples consisting of 9 samples of normal concrete and 45 samples of normal concrete + cbm additive cement. The results showed that the value of the compressive strength of concrete at the age of 28 days for normal concrete was 438.9 kg / cm2 and the addition of cbm additive cement which could increase the percentage of concrete compressive strength, 3,0% amounting to 27,11%, 3,5% amounting to 28,18%, 4,0% amounting to 29,23%, 4,5% amounting to 25,00%, 5,0% amounting to 20,79%. Keywords: K-300 Concrete, Concrete Compressive Strength, CBM additive cement
