Abstract

Self-consolidating concrete, also known as self-compacting concrete (SCC), is a highly flowable concrete that spreads into place and fills formwork without the need for mechanical vibration. SCC reduces the time and labor cost needed for concrete placement. This study is part of the proposed project by Tennessee Department of Transportation (TDOT) carried out by University of Tennessee at Chattanooga (UTC) to develop four new SCC mixtures (two Class P-SCC (precast) and two Class A-SCC (general use), and insure they meet the minimum strength and durability requirements for TDOT Class P and Class A mixtures. The objectives of the study presented in this thesis are to analyze effects of visual stability index (VSI) on both fresh and hardened properties of Class P-SCC concrete under the accelerated curing using SURE CURE system. In addition, the relationship between VSI and fresh segregation of SCC is investigated. Finally, the results of this study are evaluated to recommend performance specifications for Class P-SCC for TDOT adoption of SCC standard operating procedures

Acknowledgments

All praise to my god for guidance, support and giving me health and knowledge to do this project. May the peace and blessings of god be upon his prophet Mohamed. I would like to thank my loved ones represented in my mother Dr. Nagwa Dongola and brothers Ahmed, Tarig and Sayda, who have supported me throughout entire process, all of them by keeping me harmonious and helping me putting pieces together. I will be grateful forever for your love. I would like to express my deepest gratitude to my supervisor Dr. Joseph Owino for the useful comments, remarks and the hand by hand engagement through the learning process of this master thesis. Furthermore I would like to thank Dr. Benjamin Byard for introducing me to the topic as well for the support on the way. Also, I like to thank Alex Rollins, who have willingly shared his precious time during the process of developing the mixtures. I would like to extend my gratefulness to my Civil Engineering department represented by Dr. Onyango, Dr. Fomunung and Dr. Wu. In addition to Dr. Alp the Interim dean of Engineering College. Finally, I would like express my deepest appreciation to my friends and roommates who helped me throughout the entire process Ammar, Abdelrahman, Ahmed, Walied, Iyad, Daniel, Musab, Mujtaba, Haythem, Mariana, Nada and Marissa.
