The estimated strength values were compared with experimental values.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:The standard and non-destructive tests were performed on totally 144 cubes and 24 beam specimens produced from different concrete mixtures.
📊
Key Findings & Data:The results of the non-destructive tests carried out on beams were correlated with cube compressive strength values.
💡
Conclusion & Impact:The estimated strength values were compared with experimental values.
The standard and non-destructive tests were performed on totally 144 cubes and 24 beam specimens produced from different concrete mixtures. The results of the non-destructive tests carried out on beams were correlated with cube compressive strength values. The effects of aggregate’s type and its maximum size on the results of ultrasonic pulse velocity and rebound hammer tests were investigated. Simple charts were obtained from the test results and the use of these charts for the quality control of concrete in structural elements cast by locally available materials was discussed. Strength estimations were made using five combined models proposed by various investigators. The estimated strength values were compared with experimental values.
