STUDY OF THE INTERACTION OF AND BOND BETWEEN AGGREGATES AND HYDRAULIC BINDERS

ETUDE DE L'INTERACTION ET DE LA LIAISON ENTRE GRANULATS ET LIANTS HYDRAULIQUES

THE AIM OF THE RESEARCH IS TO ACQUIRE AN UNDERSTANDING OF COHESION PROCESS IN COMPOSITE MATERIALS. IN 1979 IT IS PLANNED: TO PREDICT THE POZZOLANIC CAPACITY OF BASALT BY APPLYING CHEMICAL CRITERIA; AN ATTEMPT WILL BE MADE TO TRANSPOSE THE METHOD TO EVALUATE THE REACTIVITY OF SOME GRANULATED SLAGS; TO STUDY THE CAUSES OF SWELLING AND DECOHESION PHENOMENA LINKED TO THE FORMATION OF SECONDARY ETTRINGITE; THE EQUILIBRIUM CHART LIME-ALUMINA-CALCIUM SULPHATE-WATER WILL BE REFINED, AND THE TEXTURE OF BINDER-AGGREGATE SYSTEMS WILL BE STUDIED AT DIFFERENT LEVELS.
