Abstract:
Contamination of basaltic rocks with clays of the montmorillonite group causes the expansion and failure of the rocks when exposed to moisture changes. When these rocks are used as concrete aggregates, contamination may produce concrete degradation. In Argentina, there are some bridge structures affected by this process. The present paper considers some results obtained by the use of different tests used for basaltic aggregates' evaluation, and a decision criterium is proposed.
