Concrete Performance With Admixtures of Electrical Steel Slag and Copper Copper Concerning Mechanical Properties

The generation of solid residues and an adequate final destiny for them is a subject that has attracted more and more research. The recycling of solid by-products as construction materials can be an alternative to reduce costs of the latter and it can also reduce the impact on the environment. Nevertheless, it is fundamental that the characteristics of these new materials be equivalent to the traditional ones or even better, if possible. In this context, the use of electric steel slag and copper slag can be a potential alternative to the admixtures used in concrete and mortars. Results of physical, chemical and physical-chemical characterizations of electric steel slags from Rio Grande do Sul and copper slags from Bahia, both in Brazil, are presented in this work. Also presented are results of compressive tests, flexural tests and Brazilian tests in concrete specimens with these admixtures, indicating the viability of their use.
