ABSTRACT: In an attempt to mitigate the environmental impact of industrial activities and the assumption of scarcity of raw materials due to the impacts experienced in the present world seek out alternatives for recycling of industrial waste generated on macro complex civil construction sector. The objective of this study was to promote a literature review of promising approaches published for introduction of industrial waste for adding or partial replacement of Portland cement. To reach this goal, we carried out a literature search which included: the consultation of selected national and international, conceptualizing the cement in the sector of sustainability and civil construction and, especially, in consultation with the research at national and international levels for characterization of the types of waste as possible to be incorporated in Portland cement. The conclusion was that there is a predisposition of waste red mud and waste of marble and granite to be recycled, with compositions similar to the raw material for the manufacture of Portland cement, having more positive results in physical and chemical analyzes on the wastes that were, according to the authors pozzolanic activities.
