The sheave leather was subjected to chemical treatment in an attempt to immobilize chromium ion in a matrix of cement. Cementitious pastes were obtained by adding different proportions of waste treated solutions (5 and 10% compared to the cement mass) and the pH and setting time (hardening) were measured. Aiming to check the leather influence in Portland cement pastes, the phases formation were observed by X-ray diffraction (XRD). The results showed that the pretreatment was effective for the waste dissolution and the pH of treated waste chemical solutions did not influence significantly the characteristics of cement paste, with a slight increase in setting time results. |
