1 Theory and Testing Methods of Self-Consolidating Concrete (SCC) CEE 8813 03/14/07 Felix Kim What is Self-Consolidating Concrete? ± “A highly flowable, yet stable concrete that can spread readily into place and fill the formwork without any consolidation and without undergoing significant separation” (Khayat, Hu and Monty, 1999)

2 Benefits ± No vibration needed ± Less labor needed ± Low noise-level in the plants and construction sites. ± Easier to pump ± Faster construction ± Improved quality and durability ± Higher strength Comparison Normal Concrete ± Slump flow: 8 ~ 11 in ± Vibration required ± Somewhat self-leveling ± No segregation SCC ± Slump flow: 24 ~ 30 in ± No vibration needed ± Self-leveling ± No segregation

4 3 Characteristics ± Filling ability Ability to flow under its own weight both horizontally and vertically upwards without honeycombing around any shape ± Passing ability Ability to flow freely through dense reinforcement without blocking ± Segregation Resistance Ability to maintain homogenous mix during and after placement, without separation of aggregate from the past, or water from solids (Petersson et al., 2002) Flow ability vs. Segregation Resistance ± Difficult to achieve both flow ability and segregation resistance Flow ability Segregation Resistance
