DIN CEN/TR 16349, DIN SPEC 18047 PDF Download

The DIN CEN/TR 16349, DIN SPEC 18047 standard provides guidance for preventing a harmful Alkali-Silica Reaction (ASR) in concrete. This standard incorporates the recommendations from RILEM TC ACS (Part 1 of AAR-7) as a basis for its content. The purpose of this standard is to help construction professionals and engineers avoid ASR, which is a chemical reaction between the alkalis in the concrete and the reactive silica present in certain aggregates. ASR can cause expansion, cracking, and degradation of concrete structures over time, leading to significant damage. This framework aims to provide clear specifications and guidelines to ensure the durability and longevity of concrete structures by mitigating the risk of ASR.
