Drawing on the speaker's many years in the field, this talk gives a comprehensive overview of concrete conservation. Beginning with the goals and approaches to conserving concrete, the talk then covers common protection systems, petrographic and chemical studies, and the design of mixes used in repairs. In order to demonstrate these techniques, two case studies are examined, including a Brutalist building and building with architectural precast. The talk ends with some recommendations on how to best approach cleaning and conservation of historic concrete buildings.
