The 2014 International Concrete Sustainability Conference held last week just outside Boston in Cambridge, MA, addressed key sustainability issues for the concrete industry. Over 60 world-renowned experts presented the latest developments related to design, specifying, manufacturing, testing, construction, maintenance and research of concrete as they relate to sustainability. Life cycle assessment, environmental product declarations, health product declarations and responsible sourcing were just a few of the topics of high interest at the conference. As always, green concrete and innovative concrete technologies as ways to help reduce concrete’s environmental footprint were important topics. In addition, the MIT Concrete Sustainability Hub held its annual Showcase and reviewed research results for the past five years at the Hub and provided a glimpse into the next five years.
