Self Consolidating Concrete - its Advantages and Disadvantages

Self Consolidating Concrete: Self Consolidating Concrete is also known as self-compacting concrete ( S.C.C. ). Self-compacting concrete flows very fast around the formwork, and it does not segregate.. The slump value of Self Consolidating Concrete is normally 455 to 810 mm based on the requirement of the project. It does not need any mechanical device or vibrator to fill the voids because
