QUALITY ASSESSMENT OF CONCRETE PRODUCTION USING STATISTICAL PROCESS CONTROL (SPC) TECHNIQUES

This article aimed to review the ability of the Palestinian construction companies to apply the basic tools of statistical process control (SPC) in their concrete production systems for process improvement. A special focus is made on improving the production process of B30 concrete since it is the most widely used type in the Palestinian market. A local company was taken as a case study to monitor the compressive strength of their B30 concrete using different quality tools such as histogram, control charts and cause-and-effect diagram. The tools implementation and data analysis show clearly that these tools can be applied in such sector effectively and used to improve production processes to save materials and money.
