1. Chloride diffusivity in red mud-ordinary portland cement concrete determined by migration tests
Red mud, which is a solid waste produced in the alumina production process, is classified as dangerous due to its high pH. In this work, the concentration of chlorides was monitored by measuring the conductivity of the anolyte, which initially was distilled water. The steady and nonsteady-state chloride diffusion coefficients were estimated from the "time la

2. Estudo da deterioração de marquises de concreto armado nas cidades de Uberlândia e Bambuí / Study if Deterioration of Constructed Concrete Skyways in the city of Uberlândia and Bambuí
In recent years the number of the constructed concrete marquees with pathological manifestations has grow in Brazil, and consequences have caused them to be structurally weak, which has generally lead to fatalities. As preventive action, it becomes necessary that the projects and construction thereof be improved in quality, that found pathological causes be

3. Inibição de corrosão em concreto armado: eficiência e comportamento do sistema tiouréia/molibdato de sódio. / Corrosion inhibition in reinforced concret: efficiency and behavior of thiourea/sodium molybdate system.
A corrosão de armaduras de concreto armado em pontes, viadutos e edifícios tem preocupado o meio técnico, pois além do custo de manutenção, há o custo indireto devido à quedas de estruturas, interdições e incômodos causados aos usuários. Entre os métodos para minimizar a corrosão, podem ser citados os inibidores de corrosão, os quais são adic
