In order to obtain self-compacting concrete (SCC) for the construction industry, an important experimental program for the evaluation of the properties of fresh and hardened concrete was conducted at INCERC Cluj-Napoca Branch. The principal objectives of the research program were: to design the mix proportions for SCC, to assess the properties of fresh and hardened SCC and to study the behavior of SCC elements subjected to different loads. The fresh SCC evaluated properties were: slump flow, passing ability, viscosity and segregation resistance.
