As a result of the mechanical tests of the samples, it was determined that the strength increase of the B5 sample at 7 days compared to the control sample was 146% higher.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:This study includes a series of experimental studies to investigate the use of bentonite clay minerals obtained from Malatya region instead of some of the cement in concrete production, and thus the effect of the samples produced by reducing the use of cement on the 7- and 28-days compressive strength.
📊
Key Findings & Data:For this purpose; %0, %5, %15, %30 bentonite clay was replaced by Portland cement CEM II 42.5 R by volume in proportions and standard mortar samples were prepared in 5 different series, including control samples.
💡
Conclusion & Impact:As a result of the mechanical tests of the samples, it was determined that the strength increase of the B5 sample at 7 days compared to the control sample was 146% higher.

Abstract
This study includes a series of experimental studies to investigate the use of bentonite clay minerals obtained from Malatya region instead of some of the cement in concrete production, and thus the effect of the samples produced by reducing the use of cement on the 7- and 28-days compressive strength. For this purpose; %0, %5, %15, %30 bentonite clay was replaced by Portland cement CEM II 42.5 R by volume in proportions and standard mortar samples were prepared in 5 different series, including control samples. Workability of fresh concrete was determined by slump test and flow-table test. Compressive strength tests were performed on 7 and 28 days on the 100x100x100 mm hardened cube concrete samples. As a result of the mechanical tests of the samples, it was determined that the strength increase of the B5 sample at 7 days compared to the control sample was 146% higher.
