The paper presents mix design and properties of SCC mixes made from poorly graded crushed limestone coarse and fine aggregate, Portland cement CEM II/A-S 42.5R and inert limestone filler as additional powder material. To compensate for the lack of fine material in the crushed sand, viscosity agent or fine quartzite sand was used. As superplasticizer, three types of copolymer-based superplasticizers were used: Mapeifluid X524 SCC, Glenium 51 and Zeta Super S. Guidelines given by Okamura and Ozawa [1] were followed by mix design and proportioning of the SCC mixes. Criteria selected for acceptance of the concrete mix as SCC mix were: slump flow value at slump flow test 700 mm or higher, funnel flow time between 4 and 10 seconds, slump flow value at combined slump flow and Jring test around 700 mm or higher and no blocking, blocking ratio at L-box test higher than 0.8 and filling ratio at filling vessel test higher than or equal to 90%.
