Kate Raskauskas ’09 Takes a ‘Crack’ at Concrete Research

Kate Raskauskas ’09, a sophomore at Georgia Institute of Technology, spent her summer working as a research assistant studying Alkali Silica Reaction (ASR) and concrete damage. ASR is the process by which alkalis (basic ionic salts), reactive silica (silicon dioxide) and moisture combine to form what’s called ASR gel, which, when it expands, causes concrete expansion and cracking. This research has important implications for understanding concrete quality and the economic/environmental impacts of reconstruction that become necessary as the result of ASR.

In the course of her internship, Kate produced more than 70 samples and more than 350 microscopic images tracking ASR damage in concrete. In the process of producing samples and images, she found ways to improve imaging time while maintaining image quality.

Says Kate: “This internship gave me the opportunity to apply what I’ve been learning in school to real-world research. It was an invaluable experience that allowed me to explore the culture of research and get a better understanding of the mechanics of a research team.”
