چکیده:

The natural pozzolan of volcanic origin has a marked influence on the physico – mechanical characteristics of the concretes. When it is coupled to a water reducing superplasticizer by a correct adjustment of the composition, it greatly improves the concrete properties. The analysis of the experimental results on pozzolan concrete at 5% content and fineness of 9565 cm2/g, in a sulphated environment, showed that it contributes positively to the improvement of its mechanical characteristics, its durability with respect to water absorption, and to the permeability to the chlorine ions as well as to the resistance to the sulphates.
