| description | I express my utmost gratitude to the Almighty Allah for the successful completion of the research work as planned.
I also express my deepest gratitude and sincere appreciation to my thesis supervisor Lt Col Mohammed Russedul Islam, PhD and Co-supervisor Lt Col Md Jahidul Islam, PhD Department of Civil Engineering MIST, Dhaka for their constant guidance, invaluable suggestions and affectionate encouragement which were extremely helpful on accomplishment this thesis.
I pay my deepest honor to Major General Abu Syeed Md Masud, BSP Chief Coordinator Padma Multipurpose Bridge Project for selecting me to undergo MSc Engineering Degree in one of the most prestigious Institute of Bangladesh. My Deep appreciation and thanks to Brigadier General Wahidul Islam, SUP, NDC, psc Head of the Department of Civil Engineering, MIST, Senior Material Engineer Moazzem Hossain and Material Engineer Gobindo Kumar from N-8 Highway Project, Material Enginner Kutub Uddin from Spetra Construction Ltd, and Tushar Kanti Kait from Max Construction ltd. I need to convey my special thanks to Abdul Monem Limited and his laboratory team lead by Material Engineer Kazi Abu Borhan for their whole hearted support for doing all maximum laboratory tests. I convey my heartiest satisfactions to the Army team who were with me all time to support my thesis works are Sgt Md Anwor Faruq, Lcpl Md Monirul Islam, Snk Md Nurul Islam, Lcpl Md Kaushikur Rahman and civil staff Lab technician Shahjahan, office staff Kamruzzaman and Aman. I remember with due respect the assistance from Nag Traders for supporting me to collect local stones from the original sources.
I recompense my respect to Professor Syed Humayun Akhter, department of Geology, Dhaka University and Dr Muhammad Hasanuzzaman, Department of Glass and ceramic, BUET for their laboratory support which has enhanced my thesis work.
I also pay deepest homage to those who helped directly and indirectly in performing the work in connection with the thesis, specially laboratory of MIST, Dhaka and Laboratory SA-3, Padma Bridge Project Area.
Finally I would like to express my profound gratitude to my respected parents, my beloved wife Ahsana Sayeed, son Mahdi Mohtasim and daughter Ma As Sama for their continuous support, encouragement and sacrifice for my thesis. Their prayers and support helped me to complete my postgraduate degree in time. May Almighty help us always and enlighten us with knowledge. |

A good number of infrastructure projects are implemented in Bangladesh during the last decade and many more are still in pipeline. In the financial year 2017-18 approximately 12.7 million tons of aggregate are used by the construction industries. Local sources could supply only 11% of those aggregate and rest 89% are collected from foreign sources. Due to the wide variation of aggregate sources performance of concrete become unpredictable in some cases. Therefore, in the present study influence of coarse aggregate characteristics on concrete properties are investigated in the context of Bangladesh. To evaluate the performance of aggregate and corresponding concrete, six widely used coarse aggregate sources are selected for this study. A series of laboratory test are conducted to evaluate the ACV, TFV, LAA, EI, and FI, specific gravity, water absorption and unit weight for all six aggregates. Additionally, chemical composition and petrographic properties are also explored. Keeping the gradation of aggregate constant, two type of concrete mix (w/c ratio 0.3 and 0.4) were prepared to cast concrete cylinders and beams by using six sources of coarse aggregate. Admixture is used in concrete mix to achieve similar workability for all concrete, especially for low w/c ratio concrete. Concrete properties including compressive, tensile and flexural strengths are determined. The study finds that physical properties of aggregate generally influence the properties of concrete, especially for concrete with 50 MPa compressive strength. The outcomes of the study will help the engineers to select appropriate sources of aggregate depending on concrete strength requirement. 2019-12-18T08:36:05Z 2019-12-18T08:36:05Z 2019-12 Thesis http://hdl.handle.net/123456789/472 en application/pdf DEPARTMENT OF CIVIL ENGINEERING |
