RHEOLOGY OF HARDENED CONCRETE WITH AND WITHOUT REINFORCEMENT AND SUBJECTED OR NOT TO THERMAL TREATMENT

项目名称：	RHEOLOGY OF HARDENED CONCRETE WITH AND WITHOUT REINFORCEMENT AND SUBJECTED OR NOT TO THERMAL TREATMENT
摘要：	THE AIM OF THE RESEARCH IS TO CONDUCT AN OVERALL STUDY OF THE BEHAVIOUR OF CONCRETE SUBJECTED TO SHORT-TERM AND LONG-TERM LOADING, E.G. STRENGTH AND DEFORMABILITY. THIS BEHAVIOUR IS INFLUENCED BY THE ENVIRONMENT AND MODIFIED BY THERMAL TREATMENT. THE STUDY OF SHRINKAGE AND CREEP FACILITATED THE CRITICAL ANALYSIS OF THE DIFFERENT MODELS OF BEHAVIOUR PROPOSED. NUMEROUS STUDIES WERE CONDUCTED OF THE INFLUENCE OF STEAM-CURING ON THE STRENGTH AND MODULUS CHARACTERISTICS AT SHORT (24 HOURS) AND LONG (TWO TO FIVE YEARS) TERM. AN EXTENSIVE SERIES OF OBSERVATIONS ON STEAM-CURED CONCRETE FACILITATED THE STUDY OF THE INFLUENCE OF THE DIFFERENT CYCLE PARAMETERS ON SHRINKAGE AND CREEP. IN 1979 IT IS ENVISAGED: TO CONTINUE THE STUDY OF THE ADDITIVE NATURE OF CREEP, ITS EXTENSION TO LIGHTWEIGHT CONCRETE AND ITS APPLICATION TO BEHAVIOUR UNDER VARIABLE LOAD; TO CONTINUE THE STUDY OF THE INFLUENCE OF HYGROMETRY ON SHRINKAGE AND CREEP, AND ON THE OTHER PROPERTIES OF NORMAL AND LIGHTWEIGHT CONCRETE; TO STUDY THE INFLUENCE OF THE TYPE OF THERMAL TREATMENT AND OF PRESETTING ON THESE CHARACTERISTICS AND SELECTION CRITERIA FOR CEMENT.
