Özet
Concrete is the most commonly used construction material. The most significant properties of the concrete are the workability and compressive strength. The use of silica fume (SF) and super plasticizers (SP) in concrete has considerably increased in recent years. In this research, three different SP in three different ratios were added to 10 % SF substitution of concrete. Slump, Ve-Be and air content properties were examined in the fresh sample concrete mixtures. In addition, the effects of 2, 7 and 28-day compressive strength and freezing-thawing resistance on hardened concrete were investigated. As a result, the highest compressive strength and freezing-thawing resistance were obtained with 1 % modification lignosulphanate SP additive concrete and 2 % modification lignosulphanate SP additive concrete, respectively.
