摘要

The main application of the granulated blast furnace slag is in the cement and concrete industries. However, there is an excess of this material in the Brazilian steel industries that justifies the research for new applications. The aim of this paper is to evaluate the compressive strength of concrete having high content of blast furnace slag cement and different types of alkali-activated slag (AAS) cement. Multi-compound activators, such as liquid sodium silicate (3% Na, mass of slag) and lime (5% of slag weight - replacement); clinker (8% of slag weight - replacement) and lime (8% of slag weight - replacement); clinker (10% of slag weight - replacement) and lime (10% of slag weight - addition); lime (2% of slag weight - replacement) and gypsum (6% of slag weight - replacement). In this research, in addition to the use as cement, fine ground granulated blast furnace slag is also used as fine aggregate. Air-cooled blast furnace slag is used as coarse aggregate leading to a concrete composed only of blast furnace slag. The choice of the activator was made in function of the obtained workability and the compressive strength of concrete. This study intends, beyond the reduction of ground granulated and air cooled blast furnace slag supplies, to contribute to the cost reduction and energy conservation, thus saving natural resources and collaborating for sustainability and environmental protection, expanding the potential market of blast furnace slag application in Brazil.
