Slump flow, inverted slump flow and "V" funnel tests were performed to characterize the self-compacting behavior of the concretes.
The properties studied are rheological (flow test, funnel test and box test), mechanical (compressive strength, tensile strength and modulus of elasticity), and microstructural (hydration composites).
Mini-slump flow and V funnel tests were done to confirm flow properties required as per the specifications.
Slump flow, J-ring and V funnel tests were carried out to evaluate the filling ability, passing ability, and viscosity of the fresh concrete.
To find the segregation resistance of the SCC mix V funnel test was carried out according to UNI 11042 (2003).

The above requirements of SCC can be measured using J ring test, slump flow test and V funnel test at 5 min respectively.
Funnel tests were carried out under clear skies with no moon, approximately two hours after sunset and lasting approximately 1½ hour.
V-funnel testing and U-test indicathatthat, when the glass sand replacement increases, the time required to flow and pass through the space between the steel bars increases, mainly because the unit weight is reduced.
STATA (V.12.1) was used to conduct Egger's test 24 to test funnel plot asymmetry.
Publication bias was assessed drawing funnel plots, and Egger Test was used to test funnel plot asymmetry.
