CONCRETE

This study investigates the effect of reinforced concrete on the safety and structural performance of residential buildings in Benin City, Edo State. The frequent reports of structural defects, premature deterioration, and occasional building failures within the city have raised concerns about the quality of materials, construction practices, and compliance with established building standards. A survey research design was adopted, involving building professionals and residential property owners across selected areas in Benin City. Data were collected using a structured questionnaire developed from relevant literature and validated by experts. Descriptive statistics such as mean and standard deviation were used for analysis. Findings from the study revealed that major factors contributing to reinforced concrete failure in Benin City include poor-quality materials, inadequate supervision, incorrect reinforcement placement, improper mix ratios, and the use of unskilled labour. The study further established that these factors negatively affect building safety by causing structural cracks, excessive deflection, corrosion of reinforcement, and in severe cases, partial or total collapse. The research concludes that strict adherence to building codes, proper supervision by qualified professionals, quality control of concrete materials, and continuous monitoring during construction are essential for improving residential building safety. Based on these findings, the study recommends enhanced regulatory oversight, professional involvement at all construction stages, and increased awareness among clients and developers on the importance of using standard materials and skilled personnel. These measures will significantly reduce the risks associated with reinforced concrete failure and promote safer housing development in Benin City
