Abstract:
Port activities generate huge amounts of waste of different types and shapes. One of the most common port activities is the export of iron ore, this is verified in the municipality of São João da Barra - RJ which has a port that exports this material from Minas Gerais, which arrives in a saving format and after the process of filtration, is shipped to its destination. Therefore, the objective of this work is to evaluate the influence of the addition of the waste resulting from the filtration process on the properties of the fresh state of mortars. Proportions of 0, 25, 50 and 100% of the waste were incorporated into the sand mass for consistency assessment, incorporated air content and water retention. The results showed that the addition of the waste caused an improvement in the properties in proportions of up to 50%, and in values above some properties are below the indicated values
