SELF COMPACTING CONCRETE CHECKS AND TIPS
When performing the slump flow test (please lift up the cone slowly ) check the speed of the flow. A too fast flow indicates that the mix will easily segregate so the V-funnel test should be the next step while a too slow flow is a sign of possible difficulties of rehology in presence of steel reinfocement (J-ring to be checked immediately).
