The dregs is a waste from the cellulose production, and its reuse is important to reduce environmental impacts. Researches has already been done to incorporate it into building materials. The present work aimed at the incorporation of dregs in the production of mortar to replace hydrated lime. The methodology adopted was the Simplex network with ten sampling points, varying the amount of cement, sand and dregs. Each mix was submitted to flexural strength, compressive strength, apparent mass density and water absorption by capillarity tests. The results were analyzed by Minitab program, obtaining the influence of each component in the mixture. The best results were observed in mixes with higher proportion of cement and less of residue. This experimental design allowed the obtainment of mixture ratios from predetermined values of the tested properties. This work indicates that addition of dregs in mortar can be an alternative to civil construction.
