LONG-TERM DEFORMATIONS OF CONCRETE

DEFORMATIONS A LONG TERME DES BETONS

THE AIM OF THE CURRENT STUDIES IS TO SHOW THE LONG-TERM EVOLUTION IN DIFFERED DEFORMATIONS WHICH DEPEND ON NUMEROUS PARAMETERS RELATED EITHER TO CONCRETE CHARACTERISTICS (CEMENT - AGGREGATE) OR TO EXTERNAL CONDITIONS (ENVIRONMENT, STRESSES). A PARTICULAR STUDY IS MADE OF: - THE INFLUENCE OF THE PROPORTION OF CEMENT, - THE INFLUENCE OF THE APPLIED LOAD, - THE VERIFICATION OF CREEP, - THE INFLUENCE OF NEW TYPES OF CEMENT (IN CONVENTIONAL CONCRETE), - THE INFLUENCE OF THERMAL TREATMENT (IN LIGHTWEIGHT CONCRETE AND CONVENTIONAL CONCRETE).
