Abstract
Recycled industrial by-products and building rubbles are widely used in the developed countries. These alternative materials successfully substitute and preserve natural raw materials. Consequently, the loading of landfills and environmental burden are substantially reduced. Unfortunately, the use of alternative materials is not yet a common practice in Slovenia. The government of the Republic of Slovenia has ratified in October 2004 “The operative program of handling with building rubbles from 2004 to 2008”, with the aim of efficiently collect and recycle these materials, where the re-use is in priority in front of the disposal. Regularly recycled industrial by-products and building rubbles that exhibit appropriate physical characteristics and long-term stability and are not hazardous to the environment (due to the leaching of the toxic substances), may be alternatively used instead of natural mineral materials. Such re-use of waste materials result in preservation of natural raw materials and in reduction of environmental burden and landfill loads. The aim of the proposed project is an extensive evaluation of the possibilities of the re-use of selected waste materials in civil engineering. The waste materials that due to their enormous quantities represent heavy environmental burden, and have at the same time high potential of applicability, will be investigated. For this purpose in collaboration with industrial partners, and for their needs, the optimal procedures will be developed for recycling of selected waste materials for their re-use in civil engineering. The procedures will be optimized and processed in such way that the alternative materials as final products will result in high quality, long-term mechanical stability, chemical inertness, and that these products will be environmentally acceptable, and their re-use also economically acceptable. The following waste materials will be investigated: building rubbles, black steel slag, white steel slag, filtered dust from the electric arc furnaces, dust material originating from steel discharging, industrial waste gypsum originating from the production of titanium dioxide.
