This is one of those things you want to know before you build or retrofit / remodel your home.
As homeowners, it’s our responsibility to ensure that our homes are not just comfortable and beautiful, but also environmentally responsible. One critical aspect that is often overlooked in residential construction is the use of Portland cement. This traditional material, while tried-and-true, contributes significantly to global carbon dioxide emissions. However, the good news is that numerous sustainable alternatives to Portland cement have emerged that can help reduce our carbon footprint. Check out these exciting, eco-friendly alternatives (and remember, a certified high-performance builder will seamlessly incorporate these into your build without a second thought!):
Your Home, Your Planet: Sustainable Cement Alternatives
- Fly Ash: A byproduct of coal combustion, fly ash can replace up to 50% of Portland cement in your home’s concrete. This not only boosts the concrete’s strength and durability but can also translate into lower construction costs.
- Blast Furnace Slag: This byproduct of iron production can replace up to 70% of Portland cement, contributing to CO2 emission reduction while improving the durability and workability of your home’s concrete.
- Silica Fume: Although silica fume strengthens and enhances concrete durability, it can make the material more brittle. So, when used, it should be with caution.
- Calcined Clays: Heat-treated clays can replace up to 50% of Portland cement in concrete, making your home’s foundational structures more resilient and resistant to water damage.
- Rice Husk Ash: A byproduct of rice milling, it can replace up to 20% of Portland cement, enhancing concrete’s strength and durability, while also reducing agricultural waste.
- CarbonCure Technologies: This innovative technology injects captured CO2 into concrete during mixing, sequestering the CO2 and adding to the concrete’s strength.
- Hempcrete: Less strong than concrete, hempcrete is a superb choice for insulation applications in your home. It’s a carbon sink, too, as hemp plants absorb CO2 as they grow.
- Geopolymer Concrete: A mix of industrial waste products, this concrete variant maintains strength and durability, comparable to traditional concrete, and produces significantly fewer CO2 emissions.
- Carbon Negative Cements: An absolute game-changer, carbon negative cements absorb more CO2 than they emit. Companies like Blue Planet and CarbonCure are pioneering the way, creating building materials with a net negative carbon footprint.
