Abstract

This paper presents the development of a vane rheometer to estimate mortar plastic viscosity and yield stress. The rheological parameters were developed from measurements using a procedure to convert the vane torque and rotational velocity data into shear stress versus shear rate relationships. The used procedure considered the locally sheared material as a Bingham fluid and computed the characteristic shear rate from Couette analogy. The apparatus was tested with three experimental programs in which many rheological parameters of mortar compositions were calculated. The obtained results validated the rheometer test procedure and confirmed that the test results are reproducible.

3. Couche limite et l'effet de la composition des bétons sur leur pompabilité

Abstract

La "pompabilité" d’un béton est conditionnée par les frottements à l’interface entre le béton et la paroi de la tuyauterie. Ces frottements sont mesurés par des appareils appelés « tribomètre ». Un tribomètre développé précédemment dans nos études a été utilisé dans ce programme expérimental. Les résultats de ce programme permettent de mettre en évidence la présence des particules fines du sable de diamètre inférieur à 0,25 mm dans la couche limite formée à l’interface béton - paroi de tuyauterie au cours de pompage, ce qui détermine les frottements à l’interface et donc la "pompabilité". Ils ont également permis de quantifier l’influence de chacun des paramètres principaux de composition du béton sur les frottements et donc sur la "pompabilité".

Abstract

International audience; The prediction and reassessment of mechanical behaviour of reinforced structures affected by delayed ettringite formation (DEF) is a major challenge for structure managers. Firstly, several experimental tests were performed in laboratory to study the influence of both uni and tri-axial reinforcements on DEF expansion. Strain decreases in reinforced directions were observed, proving that DEF expansion under restraint is anisotropic. Cracks were observed parallel to the restrained directions. No strain trans-fert occurs from restrained directions to other ones. Secondly, data provided by these results are used to fit a numerical finite element model taking into account both chemical and mechanical aspects of DEF. Finally, an element of a DEF damaged structure is modelled with the whole model and compared to on site observations.
