The aim of this paper is to study the replacement of Portland cement by ceramic plates waste into mortar. The ceramic plate waste was milled and characterized through chemical analysis and particle size analysis. Then, it was elaborated mixtures in order to replace 5, 12 and 20 wt.% of Portland cement by ceramic plates waste. In addition, the consistency indices, water absorption, void index, specific mass, tensile strength in flexion and axial compression were determined for each mixture. The results showed that the ceramic plates waste are composed by of SiO2 (69.09 wt.%) and Al2O3 (15.4 wt.%). The replacement of 5 and 12 wt.% decreased the mortar porosity. The tensile strength in flexion assays showed an increase on this property. However, the axial compression tests presented a decrease of 0.9% and 2.5% for replacement of 5 and 12 wt.%.
