Holcim’s Low-Carbon Concrete Solution: ECOPact
Holcim, a global leader in innovative and sustainable building solutions, recognizes the pressing need to address climate change by reducing carbon emissions in the construction sector. With the construction industry responsible for 38% of the world’s CO₂ emissions, Holcim is committed to decarbonizing buildings, promoting a circular economy, and enhancing living standards. As part of this commitment, Holcim offers ECOPact, a comprehensive range of low-carbon concrete solutions designed to minimize CO₂ emissions while maintaining high performance standards.
Engineered Sustainability
ECOPact is engineered with innovative low-emission materials, including calcined clay, that significantly reduce the carbon footprint of concrete production. This sustainable concrete solution is locally sourced and fully recyclable, contributing to circular construction practices. ECOPact+ takes sustainability a step further by incorporating recycled construction and demolition waste (CDW) where regulations permit, further enhancing its low-carbon profile and circularity.
Versatile Applications
Designed to meet a diverse range of structural requirements, ECOPact offers versatility in applications, from infrastructure projects to residential buildings. It can be seamlessly integrated into various structural components such as foundations, columns, beams, walls, driveways, and walkways. With a wide range of strength classes available, ECOPact complies with industry standards while offering sustainable and high-quality performance.
Real-World Applications
Boston University
In a project at Boston University, ECOPact was utilized for mass concrete foundations, resulting in a significant reduction of CO₂ emissions. Through innovative design mixes containing 20% recycled materials, the project achieved a 35 to 50% reduction in global warming potential compared to standard concrete. AgileFlow mixes, incorporating innovative cement blended with Silica Fumes, further optimized concrete placement, leading to a 24% CO₂ reduction compared to baseline concrete.
SQUARE Learning Center
HSG Learning Center in St. Gallen, Switzerland, utilized ECOPact+ from Holcim for its resource-saving and low-CO₂ concrete needs. This innovative formula includes local recycled aggregates and ECOPlanet Susteno cement with up to 20% construction and demolition waste content. By using 3,000 m³ of ECOPact+, the project offset remaining CO₂ emissions with certified climate projects, ensuring a sustainable and environmentally friendly construction process.
Properties and Benefits
ECOPact offers not only reduced carbon emissions but also energy efficiency and the use of recycled materials, making it a sustainable choice for modern construction projects. Its combination of environmental benefits and high performance makes it an ideal solution for architects, designers, and developers looking to minimize the environmental impact of their projects while meeting stringent performance requirements.
