  Abstract:  VIEW PDF: RESEARCHES ON THE REVALUATION OF THE USED SANDS FROM THE INDUSTRIAL WASTES IN THE COMPOSITION OF CONCRETE

The heritage of the past, when there wasn’t much focus on complying with norms of good practice on the environment, has now become very visible on the sites found in the areas of industrial deposits. According to the information available at national level, there are 169 deposits for industrial waste which are subject to the provision of Directive 1999/31/EC32, covering a surface of around 2765 ha.In order to diminish the quantities of waste and the problems of their storage, it is recommended to review the technological processes and maximize the revaluation of the waste, as well as evacuating and storing it in a grouped manner, for the purpose of annihilating certain toxic effects.Without minimizing the importance of risks related to industrial waste storing, we must point out that, sometimes, the decisions of prevention/reduction of environmental risks are contrary to those of economic nature, which focus, most of all, on controlling factors affecting the production from the point of view of quantity and quality. The main directions with successful attempts of revaluation of industrial waste are: cement industry, asphalt industry and construction materials.

Key words: industrial waste deposits, metallurgic waste, used sands, revaluation, concrete
