Sažetak
Self-compacting concrete has to have a high flowability and ability to fill the gaps of reinforcement and corners of molds without vibration. The composition of self-compacting concrete (SCC) has a significant impact on his properties so mix design criterions are mostly focused on the type and mixture proportions of the constituents. In this work, a designe method for SCC proposed by Nan Su eat al. [1] was tested and compared with CBI method [2, 3]. For this purpose, several mixtures of self-compacting concrete were prepared and tested. Properties of fresh mixture were determined by slump flow method, visual assessment of stability, T50 time, V-funnel method, L-box method and J-ring method. In hardened state, the elastic modulus of elasticity and compressive strengths after 7 and 28 days were determined.
