Uso de Resíduos de Couro Tipo Wet Blue como Carga na Produção de Argamassas para a Construção Civil
(Instituto de Tecnologia, 2019) ANJOS, Claudia Suellen Osório dos; SOUZA, José Antônio da Silva
The possibility of use in the manufacture of mortars using leather sawdust and sulphite copper waste (RCMS) in cement paste generates an alternative of attenuation of environmental factors. In the production of these mortars was used wet blue leather, RCMS, Portland cement II and water. This research aimed to study the physical behavior of developed mortars and elucidated their performances. Traits made were 1:3:0; 1:3:2.5; 1:3:5; 1:3:7.5; 1:3:10 and 1:3:15, both with composition established in 100 g of cement and 300 g of RCMS, varying only the quantity of leather sawdust and water, being produced 18 specimens, 3 being reference cement, RCMS and water. After 28 days of life were submitted to: water absorption, apparent porosity, apparent specific mass and resistance to axial compression. The mortars were analyzed by dispersive energy X-ray spectroscopy (EDS).
