The use of unsound basalt as concrete aggregate
Abstract Basaltic flows occur in certain regions in Brazil. Among these flows unsound basaltic rocks have been observed, when exposed to weathering cycles. The Parana river valley stands in a region where the aforementioned flows occur. Since the Parana river basin offers a high hydroelectric power potential, involving the construction of a great number of dams, each dam with a concrete volume greater than, 1,4×$ 10^{6} $ $ m^{3} $ there is a certain interest in evaluating in detail, the behaviour and conditions for use of this type of unsound rock as concrete aggregate. Special studies were carried out with concrete specimens using this type of aggregate, simulating various different weather cycle conditions. General data concerning these studies are put forward in the present paper. The comments regarding the conditions of use of this type of rock as concrete aggregate, are based upon the information gathered during the studies.
