THE CONVENTIONAL CONCRETE OF CANA BRAVA HYDROELECTRIC PLANT
The paper describes studies conducted for the Cana Brava Hydroelectric Plant on the basis of the following: the prescriptions of the project's technical specifications, with emphasis on the durability of the structures; the control of thermal-originated cracking; the use of alkali-reactive aggregates and the construction Consortium's plan that prioritized pumped concrete. The work focuses on the study of mixtures and the characterization of the Cana Brava concrete. The results indicated that the use of silica fume, through its beneficial effect in increasing concrete strength, enabled a reduction in the amount of cementitious materials, thus beneficially contributing to thermal cracking control. It also proved advantageous in preventing the alkali-aggregate reaction and in reducing permeability.
