2. Introduction Self-Compacting Concrete (SCC), which flows under its own weight and does not require any external vibration for compaction, has revolutionized concrete placement. SCC, was first introduced in the late 1980's by Japanese researchers, is highly workable concrete that can flow under its own weight through restricted …

Synthetic lightweight aggregate produced from environmental waste is a viable new source of structural aggregate material. The uses of structural grade lightweight concrete reduce considerably the selfload of a structure and permit larger precast units to be handled. Water absorption of the green aggregate is large but the crushing strength of ...

The effect of water quality on the compressive strength of concrete was evaluated in this study. A total of 100 concrete cubes (150 x 150 x 150 mm) were cast using a mix ratio of 1:2:4. The hardened concrete cubes were de-moulded 24 hours after the cubes were cast and were submerged carefully in a curing tank filled with water.
