Comparison of the Effect of Adding Coca-Cola and Sugar on Setting Time and Concrete Compressive Strength

Abstract

This study aims to compare the effect of the addition of Coca-Cola and granulated sugar on the performance of the mixture. This research is using experimental method. First, watch the effect of granulated sugar and sugar content in Coca-Cola given on the weight of cement at the initial setting time and the final setting time of cement. Then watch the compressive strength of concrete with a variety of samples. The percentage of sugar content in Coca-Cola used varies, namely 0%; 2.5%; 5%; and 15%, while the percentage of variations in the sugar content used is 0%; 0.27%; 0.54%; 1.08% and 1.62% of the cement weight with 3 specimens respectively. The test results showed that the longest setting time was obtained with a mixture of 15% Coca-Cola with an initial setting time of 1662 minutes and a final setting time of 2511 minutes, while the maximum compressive strength test results obtained a mixture of Coca-Cola 2.5% of 22.56 Mpa at 28 days and 34.95 MPa at 60 days. The higher the additional percentage, the slower the concrete will eventually become to some extent. In this study, the use of Coca-Cola produces a better value than sugar.
