Such values are increasingly guiding policy decisions on therecovery and reuse of waste generated in industrial processes. This is certainly true forsteelwork slag generated in the manufacturing process, which is rapidly turning into anattractive material for the construction industry, instead of a waste product with no secondaryuse that is consigned to landfill sites. Our contribution to the XXXVII <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong>on Housing outlines current experience concerning the reuse of ladle furnace (white) slag inthe production of masonry mortar in the construction industry. It also characterizes itsproperties and assesses its features. It studies the adherence behaviour of mortarsmanufactured with ladle furnace (white) slag obtained from secondary metallurgy, inaccordance with applicable industrial standards, comparing the results with those ofconventional mortars. Our objective is to demonstrate the benefits of this industrial byproductin the production of useful construction materials.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 92
