Concrete Flow Test – Why It Matters on Site Workability is not a guess; it is a measurable property. The concrete flow test is a key quality control method used to assess the consistency and flowability of concrete, especially for highly workable and self-compacting concrete (SCC). Purpose of the Concrete Flow Test ✔ Determines ease of placement without segregation ✔ Evaluates suitability for congested reinforcement zones ✔ Ensures uniform filling of formwork ✔ Reduces honeycombing and voids How
