Abstract:
The use of waste in the construction of Portuguese public works is feasible if there are no risks for the environment. The materials that meet these requirements in Portugal are those admissible for landfills
of inert waste, their classification being done on the basis of the comparison of the leaching values obtained in standard laboratory leach tests with the leaching limit values established in the Portuguese legislation.
This paper addresses the results of the leaching tests performed in laboratory and in the field with materials coming from electrical arc furnace steel slag produced in the Portuguese Iron and Steel Company.
