General Background The construction sector relies on ready-mix operations that maintain strict material consistency. Specific Background Washed sand serves as a primary constituent, requiring silt content limits strictly below five percent to prevent hydration disruption and compressive strength degradation. Knowledge Gap Current acceptance procedures relying on infrequent monthly testing fail to capture daily supplier variations, allowing non-compliant materials to enter the production line. Aims This study investigates supplier compliance levels and formulates systematic corrective actions using quantitative charting techniques. Results Processing data from 2961.48 tons of incoming supplies between June and August identified 443.54 tons of defective material, representing a 43 percent overall failure rate. P-chart evaluations confirmed systemic instability, recording a July deviation of 0.216 that exceeded the 0.169 upper control limit, while June and August deviations fell below the 0.130 lower control limit. Root cause evaluation identified methodological shortcomings, specifically insufficient testing frequencies and unstandardized visual inspections, as the primary drivers of excessive impurities. Novelty This research directly correlates out-of-control supply chain deviations with specific inspection deficits at the plant receiving stage. Implications Deploying real-time control charts alongside increased testing frequencies stabilizes material acceptance protocols, prevents defective component usage, and secures final structural integrity.
Highlights:
-
Examining 2961.48 tons of incoming materials identified 443.54 tons failing acceptable impurity thresholds.
-
P-chart evaluations confirmed unstable acceptance procedures, with July proportions exceeding maximum boundary limits.
-
Implementing real-time tracking alongside increased testing frequencies prevents non-compliant aggregate usage.
