Every day, concrete structures crack and erode prematurely due to Alkali Silica Reactivity (ASR), a chemical reaction that causes fissures in the material as it sets. Jon Belkowitz, a doctoral student at Stevens Institute of Technology, plans to put an end to this problem through his study of chemical reactions within concrete at the nanoscale. Taking advantage of Stevens nanostructure characterization tools and materials, his research into the optimal use of nano silica will create a new concrete mixture that will result in longer-lasting buildings, roadways, sidewalks, stairs, sewers, and dams.
