Abstract: Cement is a critical binding material in concrete construction, and its strength characteristics are highly sensitive to handling and storage conditions before use. In small construction sites, improper material storage practices are frequently observed due to limited space, lack of technical supervision, and cost-driven decisions. Such practices often expose cement to moisture, fluctuating temperatures, and prolonged storage durations, potentially compromising its physical and mechanical properties. This experimental research investigates the impact of improper storage practices on the compressive strength of ordinary Portland cement used in small-scale construction projects. Cement samples were stored under three representative site conditions: controlled dry indoor storage, covered outdoor storage, and uncovered outdoor storage. Standard mortar cubes were prepared at different storage intervals and tested for compressive strength at 7 and 28 days following established testing procedures. Statistical tools, including analysis of variance, regression analysis, and independent sample t-tests, were employed to evaluate the significance of strength variations due to storage conditions and moisture exposure duration. The results demonstrate a statistically significant reduction in compressive strength for cement stored in uncovered and moisture-prone environments compared to properly stored cement. Strength losses increased progressively with longer exposure periods, indicating cumulative deterioration effects. Regression analysis confirmed a strong inverse relationship between moisture exposure duration and compressive strength. The findings highlight the critical influence of storage practices on cement performance and structural safety, particularly in small construction sites where quality control is often neglected. The research emphasizes the need for simple, cost-effective storage interventions to preserve cement quality. The outcomes contribute empirical evidence supporting better material management practices and provide practical insights for site engineers, contractors, and policymakers aiming to enhance construction quality and durability in small-scale projects.
