Abstract: 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.
