PD CEN/TR 16349:2012 PDF Download

PD CEN/TR 16349:2012 is a standard that provides a framework for specifying measures to prevent the occurrence of Alkali-Silica Reaction (ASR) in concrete. ASR is a chemical reaction that can occur between alkalis in the cement and reactive silica minerals in aggregates, leading to the formation of a gel-like substance that can expand and cause cracking and deterioration of concrete structures.

The standard aims to guide engineers, architects, and other professionals involved in the construction industry on how to minimize the risk of ASR. It provides information on the factors that contribute to the occurrence of ASR, such as the types of aggregates, cement alkali content, and environmental conditions. The standard also offers guidance on selecting appropriate materials and mixtures, as well as the use of preventive measures such as the addition of supplementary cementitious materials or pozzolans.
