Re-engineering the Manufacturing Sector for Competitiveness: A Statistical Analysis of Sandcrete Block Quality in Minna

Abstract

The spate of building collapse in Nigeria has raised concerns about the quality of building materials, necessitating the re-engineering of the manufacturing sector for enhanced competitiveness and economic growth. This study focuses on assessing the quality of commercially produced Sandcrete blocks in Minna, Niger State. Statistical analysis, including field surveys, sampling, and laboratory experiments, was employed to evaluate the blocks' compliance with existing standards. Results revealed that the sampled blocks exhibited dimensions, compressive strength, and water absorption capacity below the specified standards. Correlation analysis showed a significant negative relationship between block age and compressive strength. The findings indicate a clear need for re-engineering efforts within the manufacturing sector to improve Sandcrete block quality. By leveraging innovative technologies, optimizing production processes, and ensuring adherence to standards, the manufacturing sector can enhance its competitiveness. Implementing these improvements will contribute to economic growth and ensure the suitability of Sandcrete blocks for safe construction practices.
