Utilização da Pedra de Barro como Agregado Graúdo para Concretos

The state of Acre has long faced a chronic shortage of rock aggregate for the construction industry due to its unavailability in the soil composition and the high cost of importing this product. On the other hand, there is an abundance of raw material for the ceramic industry, such as clay. This work presents an aggregate for concrete made from calcined clay, similar to the process used in the production of ceramic artifacts. The new product reduces construction costs in the region and enhances the quality of structures over the use of brick pieces. The results show that the strength of the aggregates is satisfactory, and the mechanical properties of the concrete dosed with usual amounts of cement confirm the technical feasibility of clay aggregates for structural concrete.
