Timbercrete is yet another green alternative for building material with many perks over industrial concrete. This came with carbon emissions almost reaching 2.6 billion metric tons, which is more than 7% of the worlds total emissions. Concrete would also need insulation, likely foam, so you would need to add that to the carbon equation. We have collated 11 green building materials that offer alternatives to concrete, and a lower environmental impact. It is a bio-composite material that is a mixture of shives and lime, including naturally hydraulic lime, pozzolans, or sand. You can expect to pay $500 or more. Blast furnace slag is a solid waste by-product from the iron extraction process performed in a blast furnace. This may seem a bit of a throwback, but there's a reason building with straw occurred as an original idea. In application, this material can take the place of traditional aggregate by as much as 20%. Tends to stain just like cement driveways, but you can remove the stain. Once they've got a few thousand foundations in service and we see how they perform I might get more excited.

It can go as high as 80% cement replacement in marine construction or structures with exposure to chloride and sulfates. Researchers Study Concrete as an Alternative to Steel for Wind Turbine Foundations and Towers The use of concrete support structures for offshore wind turbines offers many potential advantages over towers comprised of only steel, including greater durability, a longer lifespan, increased local labor opportunities, and much quieter installations. 4. The material offers a sustainable alternative to modern building materials. As an alternative, a helical pile system is a far greener alternative as it only requires a fraction of the manufacturing, a fraction of the transport costs and doesn't create soil erosion problems that the alternative does. Here are a few sustainable concrete alternatives to make it more eco-friendly or replace concrete altogether: Bamboo is a very useful material for structures like houses. All rights reserved. This can be addressed by using glass in combination with silica fume or fly ash.
