Influence of Addition of Chemically Treated Leather Shaving in the Portland Cement Mortars Characteristics

Abstract:

The growing concern with environmental issues in tanneries and the search for a technological solution to their wastes are evaluated in this study. The waste named leather shaving was chemically treated aiming the immobilization of the chromium ion in a Portland cement paste, using mortars. 28 days-aged samples were evaluated in relation to their physical properties and axial compressive strength. Results showed that the alternatives used for the pretreatment were effective for the dissolution of the material, but they impaired the mechanical strength of samples.
