Abstract

Abstract

In this paper the high carbon ferrochrome slag used as coarse and fine aggregate in the preparation of C40 concrete was carried out. The compressive strength and carbonization resistance of concrete containing high carbon ferrochrome slag weree investigated and the solidification effect of hexavalent chromium ion in cement concrete was evaluated. The results indicate that the compressive strength of concrete with high carbon ferrochrome slag at 28 days is slight higher than the ordinary C40 concrete. The resulted concrete with incorporation of high carbon ferrochrome slag is superior to the reference concrete regarding the resistance to chloride penetration and carbonization due to its surface porosity and high porosity. Whereas, the surface leaching concentration of concrete incorporating high carbon ferrochrome slag is relatively low and less than the critical value of 0.05 mg/L. From the perspective of application and environment, it can indicate that the preparation of C40 concrete with high carbon ferrochrome slag as aggregate is feasible.
