BUILDING FOR A NET-ZERO FUTURE AT BOSTON UNIVERSITY

THE CHALLENGE

• The project team needed to come up with ideal sustainable concrete solutions for the wide range of construction applications.
• With the job site located on one of the busiest thoroughfares in Boston, logistical problems needed to be addressed to ensure continuous on-time deliveries from off-site concrete batch plants.
• With concrete representing a significant portion of the structure, the use of eco-friendly, high-performance mixes was paramount to minimize the environmental footprint.
   

THE SOLUTION

• This project was ideal for ECOPact green concrete—the industry’s broadest range of low-carbon concrete mixes for high-performing, sustainable, and circular construction.
• For the mass concrete foundations pour, 4,200 cubic yards of ECOPact were delivered over a span of 15 hours—totaling 711,000 kilograms of CO2 reductions.
• The team partnered with the client and developed two proprietary ECOPact design mixes containing 20 percent recycled materials.
• These innovative mixes were designed to reduce the global warming potential (GWP) by 35 to 50 percent compared to standard concrete.
• The project’s AgileFlow mixes used an innovative cement blended with Silica Fumes. These self-consolidating mixes helped optimize jobsite concrete placement, while also providing a 24% CO2 reduction compared to a standard concrete baseline.
