ECODOR: proposta de mistura sustentável destinada à fabricação de dormentes de concreto

Abstract

Brazil is a large country and the railroads in this context play a key role enabling the transport of large volumes and also passengers, especially considering the rise of its domestic and foreign markets. This research is by a study of technical and economic feasibility of a mixture used in the manufacture of concrete sleepers, observing the environmental, social and economic problems that integrate the concept of sustainable development. In this context was used a mixture of Portland cement, fine aggregate (from the waste of the marble processing), coarse aggregate (from the stamping gneisses) glass fiber (optical fiber waste) and water, measured in compressive strength, tensile strength by diametrical complexion, the bending tensile strength, modulus of elasticity and water absorption by immersion and capillarity tests, according to the standards generally prevailing. Finally, was performed a technology planning to analyse the possible insertion of the resulting product on the market, where it was possible to conclude the viability of this new mixture.
