On Sept. 24, TTI Senior Research Scientist Anol Mukhopadhyay presented the session Evaluating the Effectiveness of Fly Ashes and Other Potential Alternatives to Mitigate Alkali–Silica Reaction (ASR) Using an Innovative Performance-based Approach. Anol was an invited speaker at the 2021 Structural Engineers Association of Texas (SEAoT) Conference Sept. 23–24.
SEAoT asked Anol to share the ASR tests and performance-based approach he and his TTI team developed using two test methods and pure solution estimation. Of particular interest was how Anol is using those tools to evaluate fly ash alternatives for mitigating ASR’s impact and addressing durability issues.
“Conventional fly ashes are gradually diminishing, and by 2030 the demand will be much higher than the supply,” says Anol. “Implementing this alternative method has great potential for addressing this critical industry issue. Further research is needed to apply the approach to other kinds of available alternatives and verify its effectiveness. I appreciated the opportunity to talk on this topic and increase awareness about the ASR phenomenon.”
SEAoT’s conference theme this year was “look to the future.” Attendees discussed emerging technologies and recent developments through training and networking in El Paso, Texas. | Learn More about the Conference
