Engineers at Washington State University have set out to test whether waste glass can improve something every American walks and drives over daily: ordinary concrete. According to a 2022 Washington State University master's thesis by Lauren Likes, advised by Professor Somayeh Nassiri, recycled glass powder replacing 20% of cement in concrete produced test mixes that grew stronger over time and resisted damage better than a standard mix. This was a controlled university lab study using test specimens, not a statewide construction policy or an already approved use in buildings.
