ABSTRACT

This Final Year Project is about the effect of aggregate size on the interfacial transition zone in concrete. Concrete is a construction material that consists of cement, commonly Portland cement, aggregate (generally gravel and sand) and water. Concrete is strong in compression but it is extremely weak in tension. This project will study about the influence of interfacial transition zone towards roncrete properties, the bond between aggregate and cement paste and the causes of weaknesses of concrete in tensile strength.

Some experiment and test should be done in laboratory to analyze the performance of design mix concrete (high tensile strength concrete). Many researches and literature review also must be done to fmd the cause of weaknesses in teusion and to recommend modification that can be made to improve tensile strength of concrete. The significance of this project is to obtain high performance concrete with exceptional high tensile strength and compressive strength for future construction and development. The result of this project also minimizes the cost for construction by reducing the need of steel reinforcement in structure.

ACKNOWLEDGEMENT

First and foremost, I would like to thank God for His guidance and help, for it is through His blessing that I am able to complete this Final Year Project. Thank you for guiding me towards completing this project.

Next I would like to express my heartfelt gratitude to my supervisor, Dr. Victor Rivera Macam Jr. He has done a tremendous job in monitoring and guiding me throughout the project. Thank you for giving me a chance to involve myself in the final year project under his supervision.

I also want to thank the following parties:

Those lecturers who have given their advice regarding the project

Lab executive and lab technicians who have given their helps and times in order to successfUlly conduct all lab testing

Universiti Teknologi PETRONAS (UTP), especially to Civil Engineering Department.

This deepest appreciation also dedicated to my supportive family and friends who have been giving me strength towards completing this project and to all individual and parties that have directly or indirectly involved in this fmal year project.
