✦ Synopsis

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 properties due to the complicated interaction of hydration with magnesium, chloride and sulfate attack. Mineral admixtures, in combination with a long initial cure, provided the most durable concrete. Concrete with 65% slag had the best overall durability to the brines tested.

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 (

Ice formation measurements using low temperature calorimetry (CAL) were made on non-air entrained high strength concretes (HSC) before and after exposure to rapid freeze/thaw cycles in water (ASTM C666 proc. A). The purpose was to explore the relationship between water absorption during test, change
