Abstract：The influence of ferro-nickel slag powder on the sulfate attack resistance of concrete and the corresponding mechanism were investigated by measuring the porosity and charge passed through the concrete and the compressive strength loss below and after the concrete experienced a dry-wet cycle in a sodium sulfate solution and immersion in a high temperature sodium sulfate solution. The results show that the effect of the two kinds of sulfate attacks were the same. The connected porosity of the concrete increases and its sulfate attack resistance decreases with increasing electric furnace ferro-nickel slag powder content. The connected porosity of the concrete decreases, the chloride ion penetrability decreases and its sulfate attack resistance increases with increasing blast furnace ferro-nickel slag powder with mass fractions less 30%. The sulfate attack resistance of concrete is enhanced less by adding blast furnace ferro-nickel slag powder than by adding blast furnace slag power especially at high powder mass fractions.
