One of the great causes of the human being impact in the nature is the withdrawn of raw materials for the industrialization of products. The production of cement Portland is responsible for 5-7% of the total global emissions of CO2 and hence by the global warming. Among the alternatives to overcome this issue is to investigate solutions regarding the cement Portland production, in order to reduce the negative impact. Therefore, the present research had the objective of evaluating the compressive strength of commercial Portland cement slurries molded with the proportions of reduced environmental impact agglomerant produced with red ceramic tile residue instead of the clay extracted from the nature commonly used in the process. As a complement, the objective is also to characterize the raw materials used through X-ray Diffraction (XRD), evidencing the presence of its compounds. It was concluded that the raw materials employed present the compounds necessary for the production of the alternative agglomerant and the tests of resistance to compression showed similar or superior resistance of the cement with proportions of the alternative agglomerant in relation to the comercial one.
