The rheological properties of fresh high-performance concrete were investigated with a new rheometer for concrete, BTRHEOM. It was found that, in a steady state, this category of concrete, without or under vibration, behaves as a Bingham material, and can be characterized by the shear yield stress (

The addition of polysaccharide gums to cement pastes has a considerable effect on their rheological properties. These admixtures are currently used in several practical applications such as anti-bleeding agents, anti wash out admixtures, and pump and sag resistance additives. The success of these ap
The durability of six concretes exposed to magnesium brine was monitored for 24 months. These concretes incorporated ground granulated blast furnace slag, silica fume, and fly ash. The Young's moduli, chloride penetrations, and median pore diameters were measured. There was a cyclic nature to these
Capillary pressure and plastic shrinkage have been measured simultaneously. The action of capillary pressure in fresh concrete is assumed to be the cause of plastic shrinkage. Characteristic results are presented to verify the essential statements of this hypothesis. The influence of water-cement ra
Industrial waste is very often immobilized in metallic casks which are then installed in concrete confinement enclosures. High performance concrete types can provide an elegant solution for the storage of waste, with the possibility of avoiding double-wall confinement. This study analyses the behav
The concept of high packing density has been recently rediscovered, as a key for obtaining ultra-high-performance cementitious materials. First, this paper presents two models allowing to predict the packing density of a particle mix. These models are derived from the Mooney's suspension viscosity m
