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

β¦ Synopsis
The lack of durability of reinforced concrete structures often refers to the corrosion of the reinforcing steel and the subsequent spalling of the cover concrete. With the use of water sorptivity in quantifying the quality of concrete, this paper discusses the deficiencies in the common practice of specifying concrete for reinforcement protection. The paper also demonstrates how water sorptivitv can be used as a simole oerformance criterion for specifying durable concrete.

The current practice of specifying concrete for reinforcement protection is often by the standard 28-day compressive strength, water-cement ratio, and cement content. However, this form of specification may lead to misinterpretation. This paper offers an alternative approach based on performance cri
