Self Consolidating Concrete - Overview of SCC - Concrete

Self-consolidating concrete (SCC) is recognized as one of the greatest advances in the concrete industry. Using new admixtures and some mix modifications, we can now produce concrete that flows easily without segregating (where the coarse aggregate separates from the cement paste). Concrete that segregates loses strength and results in ...

Effects of Recycled Concrete Aggregates on the Compressive

Apr 04, 2012  The effectiveness of internal curing of high-strength self-consolidating concrete (SCC) using saturated recycled-concrete aggregates is examined in this study. Tests were performed on SCC using natural rock aggregate (NR-SCC) and recycled-concrete aggregate (RC-SCC). Fresh concrete tests included slump-flow, slump-flow with a J-ring, and L-box ...

Concrete recycling - Wikipedia

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into
