STUDY OF SMALL-SCALE MODEL MICRO-REINFORCED CONCRETE STRUCTURES

ETUDE DE MODELES REDUITS DE STRUCTURES EN MICRO-BETON ARME

In order to check new design methods and to forecast the behaviour of real structures, it is necessary to perform many tests. If the laws of similitude apply, the tests can be carried out on models thus greatly reducing the costs of the equipment needed. The aim of this study is to investigate whether the behaviour of micro-reinforced concrete models is sufficiently near that of reinforced concrete structures. The use of micro-concrete is of great interest since the heterogeneity and composite nature of the material is taken into account in the tests. Furthermore such models enable failure, cracking and deformation phenomena to be studied in the fissuration phase; such investigations cannot be conducted on a model made of homogeneous materials. After the relations of similitude and scale of reduction have been defined, a study is made of the composition of the materials used. The characteristics of the hardened materials are examined and compared. /TRRL/
