The effects of Visual Stability Index (VSI) on fresh and hardened properties of Self Consolidating Concrete (SCC) under accelerated curing condition

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
