Self-compacting concrete was developed in 1980’s to achieve durable concrete structures, with introduction of superplasticizers in the ordinary cement concrete. Since then various tests and experiments are done to reveal its various properties and application. The benefits of SCC

Slump Flow Test:

This test is conducted to measure the flow ability of self-compacting concrete. The measured characteristics of slump flow test are filling ability, viscosity and stability. 2. J Ring Test:

This test helps to find out the passing ability of the concrete. The apparatus consists of rings of reinforcing bar around a standard slump cone. The time taken by the concrete to completely flow is measured and then the length to which the concrete spread is measured. Fig 1. J Ring apparatus

3. L Box Test:

This test is also done for checking the passing ability of the concrete. The apparatus is in L shape and consist of a barrier through which the SCC is allowed to flow. The time taken by the concrete to pass the barrier and the height of the mix at the lower end of the apparatus is measured. Fig 2. L box apparatus

4. V Funnel Test:

This test helps to measure the viscosity of the SCC, it consists of a V shaped apparatus with an opening at the bottom through which the concrete flows. The time taken by the concrete to empty the upper portion measures the viscosity of the mix. Fig. 3 V funnel apparatus
