Özet:

The effect of sulfate is one of the important outside influences in the deterioration of concrete and reinforced concrete structures. In this study, pozzolanic additions were added to changing in ratio 20% by weight of the (PÇ. 42.5) portland cement. Prepared samples were exposed in 150 g / L Na2SO4 solution prepared according to ASTMC 1012 for 5 months . In addition, a group were kept in water and compressive strengths are presented as a comparatively. Pozzolanic addition materials were added to portland cement (PÇ 42,5) 0%, 10%, 20%, 30% and 40%by weight of the cement. The highest compressive strength demonstrative of the prepared concrete samples were determined optimum mixing ratio. The highest compressive strength were obtained with % 20-30 pozzolanic concrete samples.
