mixing. The rate of hydration is dependant on the temperature of the concrete mix. As time passes the fluid concrete stiffens and loses workability and sets about 5 or 6 hours after mixing, depending on the concrete temperature. The now hardened concrete gains strength with time, with the hydration reaction ceasing if the concrete dries out.

strength of concrete but helped in providing added workability to the concrete mix. This further helped in the formation of self-compacting concrete. After replacing various percentages of virgin aggregates by RAP it was observed that the 28 day strength of the concrete remained above 25MPa for up to 30% replacement.

1. Introduction. Self-compacting concrete (SCC) has widely been used in many concrete structures of massive or irregular geometry. SCC is known for its excellent deformability, high resistance to segregation, and successful use in congested reinforced concrete structures characterized by difficult casting conditions that do not allow for vibration (Güneyisi, 2010).
Self-Consolidating Concrete...Delivers Efficiency, Beauty, Savings and More. Self-consolidating concrete, also known as self-compacting concrete (SCC), is a highly flowable, non-segregating concrete that spreads into place, fills formwork, and encapsulates even the most congested reinforcement, all without any mechanical vibration.
