A Device for Studying Fresh Concrete Friction

CODEN: CCAGDP

Abstract

Many civil engineering applications are confronted with problems caused by friction (wear, head losses, etc.). A tribometer for fluid material was therefore developed. The principle consists in pressing fresh concrete samples against a moving metal surface and measuring the tangential force. The validation of this new instrumentation is presented. Results obtained on two concretes show that the friction does not follow Coulomb's Law. The main parameters (pressure, velocity) involved during formwork filling are taken into account.
