Abstract :

Cement and concrete are essential engineering materials in the construction industry, with cement acting as a key binder in concrete. When modifications are needed to either accelerate or delay setting time, admixtures play a crucial role. The industry continues to seek effective retarding admixtures and optimal dosage levels, particularly for ready-mix concrete. Common retarders, both organic (e.g., lignosulfonates, hydroxycarboxylic acids, phosphonates, sugars) and inorganic (e.g., phosphonates, borates), slow the cement-water reaction by altering hydration product growth or restricting water penetration. However, research is still evolving to determine the ideal dosage and materials for these applications. In response to this need, this study explores the use of sugar as a retarder in concrete while preserving cement strength. Sugar was added at 5%, 10%, 15%, and 20% of cement weight, and its effects on consistency, setting time, compressive strength, properties were evaluated at 7, 14, and 28 days. Findings indicate that setting time increases with higher sugar dosages, but for maintaining strength, a dosage below 5% is recommended for industrial applications.
