Ohio has substantial lands impacted by surface mining for coal and an active steel industry. Steel industry slags have been used as liming compounds for agriculture and acid mine soil reclamation. This 3-year study evaluates slags from Ohio steel mills in greenhouse trials where these materials are compared to reagent grade CaCO 3 in their ability to improve plant growth on acid mine soil. The ...

Innovative approaches are under research to study the resistance of chloride ion penetration in concrete containing ions, minimize impact test errors coastal reinforced (RC), which is helpful design RC structures. In this study, diffusion depth, free concentration and coefficient chloride, iodide ions with different curing ages GGBFS content were measured by Rapid Chloride Migration Test (RCM) ...
