Book Description
ON PRESENTE ICI DEUX TYPES DE MODELISATIONS, AINSI QUE DE NOMBREUSES DONNEES EXPERIMENTALES, PORTANT SUR LES DEFORMATIONS DES BETONS ET EN PARTICULIER CELLES DES BETONS A HAUTES PERFORMANCES. LA PREMIERE A POUR BUT DE PREVOIR LES AMPLITUDES DES DEFORMATIONS INSTANTANEES, DE RETRAIT ENDOGENE ET DE FLUAGE PROPRE, EN FONCTION DE LA FORMULATION. ON UTILISE POUR CELA UNE APPROCHE PAR HOMOGENEISATION, EN ADAPTANT LE MODELE BISPHERE DE HASHIN AU CALCUL DU MODULE DU BETON. LA DEMARCHE DE MODELISATION, FONDEE SUR LA PRISE EN COMPTE DE LA COMPACITE REELLE DU SQUELETTE GRANULAIRE, ABOUTIT A UNE GEOMETRIE TRISPHERE. ON FAIT LE CHOIX, APRES L'AVOIR JUSTIFIE, DE FIXER LES COEFFICIENTS DE POISSON A UN CINQUIEME. PUIS, ON APPLIQUE LE MODELE TRISPHERE AU CALCUL DES AMPLITUDES DE FLUAGE PROPRE ET DE RETRAIT ENDOGENE. LES PARAMETRES PRINCIPAUX DE FORMULATION (RAPPORTS EAU SUR CIMENT, FUMEE DE SILICE SUR CIMENT, PROPORTION GRANULAIRE, CLASSE DU CIMENT) SONT PRIS EN COMPTE. L'APPROCHE APPLIQUEE AU FLUAGE EST CONFORTEE PAR UN CALCUL VISCOELASTIQUE LINEAIRE. DANS LA DEUXIEME APPROCHE, ON PROPOSE UN MODELE SIMPLIFIE, DE TYPE REGLEMENTAIRE, POUR LE CALCUL DES DEFORMATIONS DES BETONS A HAUTES PERFORMANCES EN FONCTION DU TEMPS, ET D'UN NOMBRE LIMITE DE PARAMETRES. LES APPORTS PRINCIPAUX DE LA MODELISATION CONCERNENT LA PRISE EN COMPTE DE L'AUTODESSICCATION, DE LA MATURITE ET DE LA RESISTANCE DU MATERIAU AU MOMENT DU CHARGEMENT. LE MODELE A ETE VALIDE D'APRES DE NOMBREUSES DONNEES, ET POUR DES BETONS DE MATURITES TRES VARIABLES AU CHARGEMENT, VARIANT DE SEIZE HEURES A PLUS DE DEUX ANS. ELABORE DANS LE CADRE DE L'ASSOCIATION FRANCAISE POUR LA RECHERCHE ET L'ETUDE DES MATERIAUX ET DES STRUCTURES (AFREM), LE MODELE EST PROPOSE COMME ANNEXE AU REGLEMENT FRANCAIS DE BETON PRECONTRAINT (BPEL), POUR LES BETONS COUVRANT LA GAMME B60-B80

Book Description
Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Book Description
This book addresses probabilistic methods for the evaluation of structural reliability, including the theoretical basis of these methods. Partial safety factor codes under current practice are briefly introduced and discussed. A probabilistic code format for obtaining a formal reliability evaluation system that catches the most essential features of the nature of the uncertainties and their interplay is then gradually developed. The concepts presented are illustrated by numerous examples throughout the text. The modular approach of the book allows the reader to navigate through the different stages of the methods.

Book Description
The book examines advanced, non-standardized techniques that have been developed for determining different properties of cement paste, mortar and concrete, and provides state-of-the-art information on methods for monitoring hydration-induced changes in cement-based materials (CBMs). These methods are often nondestructive and allow quasi-continuous monitoring covering the time span from placement of the material to formation of a fully hardened cement composite. The book also presents various applications of acoustic emission for characterizing fresh concrete, recent developments in ultrasonic methods for characterizing CBMs since placement, application of ambient response methods for measuring elastic modulus, methods for determining deformational characteristics of CBMs since setting and methods for in situ measurements of stresses in concrete elements during hardening.
