Self-compacting concrete (SCC) is a special type of concrete which can be placed and consolidated under it’s own weight without any vibration effort due to it’s excellent deformability, and which at the same time is cohesive enough to be handled without segregation or bleeding.
The workability of self-compacting concrete is measured by the usual slump cone having a base diameter of 200mm, top dia 100mm, and height 300mm. The slump cone is to be placed as usual upon a base plate square in shape is having at least a 700m side. Concentric circles are marked around the center point where cone is to place. A firm circle is drawn at 500mm diameter. (more…)
