Concrete Cancer

Original Presentation Date: March 15th, 2023

Presented by Paolo Benedetti, IWI

Alkali Silica Reaction (ASR) is often referred to as "Concrete Cancer", an affliction that destroys cementitious structures from within by way of a complex set of runaway chemical reactions. Builders who do not understand ASR and fail to take preventative measures become exposed to catastrophic project failures. The good news is that ASR can be reliably prevented by applying basic knowledge and proven methods. This course defines ASR in layman's terms and covers prevention from both the technical and business perspectives.
