Concrete Materials for Durability and Sustainability
Modern concrete design and construction objectives often necessitate optimization of concrete mixtures for reduction of portland cement. Techniques for optimization developed at MJ2 Consulting, collectively called Low Heat Performance Concrete (LHPC), have resulted in some of the lowest carbon concrete mixtures used to date in the construction industry, ranging from 15-50% clinker. When project conditions necessitate high strength, high flowability/self-consolidating, or long service life, optimization of cementitious materials becomes more critical. To address these challenges, we will discuss project experience and case studies where concrete has been optimized for both flowability or durability and low clinker content.
