Into this paper there are presented physical and mechanical properties of control samples from self-compacting concrete realized with fly ash and silica fume (like powders) and superplasticizer. The slump of fresh self-compacting concrete was 680 mm, L-box h1/h2=0.92 and V-funnel = 12 sec. There were realized prismatic samples with dimensions 10 x 10 x 30 cm. The control samples were kept into laboratory curing conditions. The testing ages were at 28 days and 9 years. At 28 days age, the compressive strengths on p...
