The influence of chemical admixtures on the properties of Self-Compacting Concrete (SCC) was investigated. All types of used admixtures were the same percentage of 1.4% according technical data. The water – cement ratio was maintained at 0.36 for all mixes [8] [9]. The paper presents test results for acceptance characteristics of flow ability, resistance against segregation, and passing ability of self-compacting concrete in fresh state. Further, mechanical properties of hardened concrete such as compressive, tensile and flexural strength at the ages of 7 and 28 were also determined, and results of Absorption and sorptivity result are included here. The results indicate that Sika ViscoCrete 3425 and AddiCrete BVS 100 give better results for all tests.
