Cement is moisture sensitive material, which can interact with surrounding atmosphere that can cause first hydration reactions. Factory cement reaches the site after some days or months, and it may be store for several months, which leads to loses of its property and strength development of concrete. This research was, therefore, amid to investigate cement storage practice and its impact on cement properties and strength of concrete in Bahir Dar University construction projects. Qualitative, quantitative, and experimental methods were implemented through observation, questionnaires, and laboratory investigations. To support findings from questioner survey cement was stored under actual site store conditions for 60,120 and 180 days to investigate the impact of stored cement, and the fresh/3day cement was used as control. From the study the majority of the respondents were found having reach experience and had information about the storage of cement and its impact on the concrete strength development. 70% of the projects purchased cement from both factory and wholesaler and stored it in corrugated iron sheet warehouse up to the storage capacity from 60 to 180 days. It’s due to transport and design problems. It can, therefore, be concluded that storage duration and conditions affect the property of cement and strength of concrete negatively. As a result, prepare storage plans, dry and moisture-proof stores, stacked on wooden planks, and giving training for employees are the very major factor for the management of cement storage in construction projects.
