Influence de la concentration et de la dimension des granulats vis-a-vis de la poussee du beton frais sur une paroi coffrante (effects of aggregate concentration and size in fresh concrete pressure on formwork walls)

摘要

Our paper focuses on the influence of both the size and concentration of the aggregate-paste mixture when fresh concrete presses against formwork walls. The testing equipment used consists of a formwork fitted with force and displacement sensors. The experimental study includes water with well-known rheological characteristics, which has allowed us to validate the experimental process.
