Restrained shrinkage testing of high-performance concrete modified with structural lightweight aggregate

This paper deals with the development of low-shrinkage, high-performance concrete (HPC). It presents results of structural laboratory testing of large prismatic HPC specimens under restrained shrinkage and tensile creep. It presents a systematic testing approach including a description of the theoretical background and the experimental apparatus.Ce document traite de la mise au point d'un b\ue9ton haute performance (BHP) \ue0 faible retrait. On y pr\ue9sente les r\ue9sultats d'essai de r\ue9sistance en laboratoire de sp\ue9cimens de BHP prismatique de grandes dimensions, en conditions de retrait limit\ue9 et de d\ue9formation \ue9lastique. Une m\ue9thode d'essai syst\ue9matique est pr\ue9sent\ue9e, qui comprend la description de l'arri\ue8re-plan th\ue9orique et le syst\ue8me exp\ue9rimental.Peer reviewed: YesNRC publication: Ye
