Concrete is a basic construction material. It is a dense, durable, and impermeable substance that is used to build many structures, including roads, bridges, and basements. However, concrete emits significant amounts of carbon dioxide, making it one of the largest sources of greenhouse gas emissions in the world.
One way to reduce the environmental impact of concrete production is to recycle waste materials. Materials like lead slag, blast furnace slag, and industrial by-products can be reused in the manufacturing process. These materials are an important part of the construction sector and can help to lower emissions.
Another option is the use of timbercrete, an eco-friendly building material made from wood chips and concrete. This is lighter than conventional concrete and can be used to create pavers or bricks. Timbercrete is also fire-resistant and long-lasting.
AshCrete is a stronger alternative to concrete that is produced with fly ash instead of cement. In fact, this eco-friendly concrete has twice the strength of Portland cement.
The ECO-Binder project is a multi-year initiative funded by the European Union and focused on developing a more environmentally friendly approach to concrete manufacturing. The project is designed to reduce carbon emissions and improve comfort, safety, and stability in buildings.
A new type of concrete, called geopolymer, is another eco-friendly alternative. This durable, human-made material can be used in 3D printing for automated construction.
New concrete is based on a mixture of limestone and clay. It could replace up to half of traditional Portland concrete.
