| description | I would like to begin by expressing my sincere gratitude to Almighty Allah, the Most
Gracious and Merciful, for allowing this thesis work to be completed successfully.
I want to extend my heartfelt appreciation to my thesis supervisor Lt Col Md. Jahidul Islam,
Ph.D., Engr’s, Associate Professor, Department of Civil Engineering, MIST, and I would
like to express my sincere gratitude for all of his advice, support, and tolerance throughout
my research project. His vast expertise and considerate criticism were extremely helpful in
guiding the course of my research and honing my technical abilities.
I also appreciate the helpful advice and ideas provided by Assistant Professor Md. Shahjalal.
His guidance has enabled me to strengthen my research and write more effectively.
Additionally, I owe a debt of gratitude to the lab assistants Mr. Anwar, Mr. Oliur, and Mr.
Tanvir who kindly gave of their time, wisdom, and experiences.
Thank you all for your contributions, support, and encouragement. Without your help,
completing this research project would have been impossible. |

The disposal of recycled concrete and plastic waste is an environmental concern. Hence, using this recycled aggregate (RA) and waste polypropylene (PP) aggregate in new concrete can provide a workable solution for disposal. Incorporating these waste or recycled materials in concrete will introduce more inhomogeneity, voids, and weaker interfacial transition zones (ITZs). Therefore, the replacement percentages of recycled aggregate (RA) and PP aggregate, and the shear-span-to-depth ratio of the reinforced concrete beams have been examined in this study. A total of 24 longitudinally reinforced concrete beams with 1100 mm length, 100 mm width and variable depth (150 mm, 200 mm, and 300 mm) are made. Additionally, waste polypropylene (PP) is acquired through a procedure and incorporated into the concrete as a partial replacement of coarse aggregate. Four distinct polypropylene aggregate (PPA) replacement percentages 0%, 5%, 10%, and 15%, with natural aggregate (NA) and RA are considered. The beam specimens are subjected to a fourpoint bending test at 56 days. The peak load and corresponding deflection, shear capacity at first crack, ductility, toughness of the beam, and strain in the steel and concrete are all measured in this test. According to the test results, adding 5% of PPA with NA concrete increases shear capacity by 8.1 % to 9.8%. Except for one case with a 200 mm depth beam, RA concrete also shows a rise in shear capacity for 5% PPA. A similar trend is also observed for the peak load. Peak load up to 24.3% and 22.6% is observed with 5% PPA in NA and RA concrete. Yet, if more PPA is added, the shear capacity and peak load decrease. The application of RA in concrete reduces the shear capacity and peak load. Polypropylene and recycled aggregate show an increase in the ductility of the beam, especially with 5% PPA. Based on the test results, it is concluded that up to 5% PPA can be adopted in concrete with NA and RA. 2024-06-11T05:47:00Z 2024-06-11T05:47:00Z 2023-08 Thesis http://dspace.mist.ac.bd:8080/xmlui/handle/123456789/822 en application/pdf Department of Civil Engineering, MIST |
