Alkali-silica reaction (ASR) is a slow, insidious chemical process that gradually breaks concrete apart from the inside. NIST research engineers share insights on how ASR damages critical infrastructure like bridges or nuclear power plants, and they explain the cutting-edge techniques they use to detect and assess this major form of degradation. Whether you're an engineer, scientist, policymaker or just curious, this video will introduce you to this little-known but high-stakes problem in the infrastructure.
