In 2022, a Washington State lab study replaced 20% of cement with recycled glass powder; 56-day strength rose 19% with steel milling, while surface resistivity improved 150% with ceramic milling
Washington State University engineers are testing recycled glass powder as a cement substitute. This waste material could potentially improve concrete strength and durability significantly. Making cement is energy-intensive and emits substantial carbon dioxide emissions annually. Recycled glass powder showed increased strength and better resistance to water and chloride ingress.
