Performance Of High-Volume Fly Ash Self-Compacting Concrete Exposed To External Sulfate Attack, Tareq S. Al-Attar Dr., A. A. Taha

International Conference on Durability of Concrete Structures

The high-volume fly ash concrete, HVFAC, could be defined as any concrete mix having fly ash content larger than 50 percent of the total cementitious materials content. Due to the availability of fly ash in large quantities globally with low cost, HVFAC could be considered as a solution for the environmental impact of Portland cements. In this study the durability of two high-volume fly ash self-compacting concrete, HVFASCC, mixes exposed to the effects of two sulfate aggressive solutions was investigated. The fly ash, class F, contents for these mixes were 50 and 60 percent by weight of Portland cement. The …


Effect Of Chloride Exposure Condition On The Performance Of Concretes Containing Pfa, Paraic Ryan, Alan O'Connor Nov 2019

Effect Of Chloride Exposure Condition On The Performance Of Concretes Containing Pfa, Paraic Ryan, Alan O'Connor

International Conference on Durability of Concrete Structures

Over the past number of decades the use of different supplementary cementing materials have been investigated, with a view to increasing the resilience of reinforced concrete to chloride-induced corrosion. The slow nature of chloride-ion ingress has meant much of the information available on the relative performance of different concretes has been derived from accelerated testing, with the majority of these tests conducted under fully saturated conditions. While there is merit to such practices, there is also a need to examine the relative performance of different concretes under unsaturated conditions. This need is highlighted by the fact that reinforced concrete elements …
