Alkali–silica reactions (ASRs) cause cracking issues in precast concrete bridge structures. In collaboration with Texas A&M Transportation Institute (TTI) Assistant Research Scientist Kai-Wei Liu, TTI Senior Research Scientist Anol Mukhopadhyay developed two ASR test methods now accepted as American Association of State Highway and Transportation Officials (AASHTO) standards, as well as a four-step process for […]

Mukhopadhyay Develops Test Methods for Cracking-Resistant Concrete Supporting Bridges
Alkali–silica reactions (ASRs) cause cracking issues in precast concrete bridge structures across the United States. Anol Mukhopadhyay, Texas A&M Transportation Institute (TTI) senior research scientist, developed two ASR test methods and a four-step process for formulating ASR-resistant concrete mixes. Mukhopadhyay notes that TTI Assistant Research Scientist Kai-Wei (Victor) Liu’s collaboration in the lab was key […]
Cracking under Pressure: How Moisture and Heat Affect ASR and DEF Structures
Texas weather runs the gamut — cold winters in some areas, occasionally heavy rains, times of drought and always baking summer heat. Concrete structures are built to last, but it’s the little things that get you sometimes. Little things like moisture and heat over time can trigger reactions in concrete structures that cause cracking and […]
