Self consolidating concrete strength
Charge passed was measured in samples cured for 1, 3, 7, 14, 28, and 40 days of curing.All mixes out-performed the control mix in terms of resistance to chloride penetration.SCC has also been described as self-compacting concrete, self-placing concrete, and self-leveling concrete, which all are subsets of SCC.

Question: Consolidation of concrete—required or not?
Self-consolidating concrete is achieved by use of the proper dosage of a high-range water reducing admixture and a viscosity-modifying admixture when needed to ensure stability and eliminate bleeding and segregation at the target spread.In this paper, the durability and strength of self-consolidating concrete (SCC) is assessed through development and testing of six binary mixes at fixed water-to-binder (w/b) ratio of 0.36.In each of the six SCC mixes, a different percentage of cement is replaced with fly ash.SCC concrete is usually defined as having a spread of 18 to 30 inches wide, making it possible to place concrete under difficult conditions.The viscosity, as visually observed by the rate at which concrete spreads, is an important characteristic of plastic SCC and can be controlled when designing the mix to suit the type of application being constructed.
