Abstract
This experimental study examines the effect of adding sugar powder to concrete on its compressive strength. The research explores how sugar powder, when used as an additive in concrete mixtures, alters the concrete’s structural performance, particularly in terms of its ability to resist compressive forces. Through systematic testing and analysis, the study aims to determine the extent to which sugar powder can influence the strength and durability of concrete, offering insights into potential applications and benefits of this unconventional additive in construction materials. The primary objective of the study was to evaluate how different concentrations of sugar powder affect the mechanical properties of concrete, particularly its compressive strength, when used in combination with different brands of cement. For this purpose, concrete cubes with dimensions of 150 mm × 150 mm × 150 mm were prepared, incorporating sugar powder at varying levels, specifically 0%, 0.05%, 0.1%, 0.15%, and 0.2% by weight of the cement content. The cubes were subjected to standard water curing procedures to ensure proper hydration, and the compressive strength was measured at two key curing intervals – 7 days and 28 days – allowing for a comprehensive evaluation of the strength development over time. The experimental findings revealed that incorporating sugar powder into the concrete mix notably affected its compressive strength. The specimens with sugar concentrations of 0.1% and 0.15% showed the most considerable enhancements in strength, highlighting the positive influence of these specific sugar concentrations on the concrete’s structural performance. These specimens exhibited superior strength compared to the control group, which did not include any sugar powder. On the other hand, the higher concentration of 0.2% showed a slight decrease in strength compared to the optimal levels, suggesting that there may be an upper limit to the beneficial effects of sugar powder as an admixture. The study further explores the potential mechanisms by which sugar powder acts as a retarder in the hydration process, delaying the setting time of the concrete and enhancing its workability without compromising its strength. This research provides valuable insights into the use of sugar powder as an additive in concrete, highlighting its potential to improve the compressive strength of concrete under controlled conditions. The findings could lead to more effective mix designs and broaden the scope for sugar powder as an eco-friendly alternative to traditional chemical admixtures, offering both economic and performance benefits for specific concrete applications.
