Abstract:
This course explores deterioration of concrete due to sulfate attack, a complex process characterized by multiple manifestations including volume expansion, cracking, spalling, softening of the cementitious matrix creating mushy concrete. Sulfate attack can be classified as internal or external to the cementitious matrix. The underlying damage of sulfate attack can be chemical or physical deterioration. The course scope involves theoretical and experimental aspects of different forms of sulfate attack as well as case studies. This course is an effort to compile current developments in research and standards, and educate practitioners and researchers about this concrete durability issue and its underlying mechanisms. And the effects of supplementary cementitious materials on mitigating external sulfate attack on concrete exposed to sulfates.
