Is there anything better than concrete?

Finding Sustainable Alternatives to Concrete Alternatives made from recycled materials, such as ferrock, ashcrete, timbercrete, and hempcrete, tend to require less carbon than concrete and also help recycle waste materials such as steel dust and straw. Recycled materials, such as steel dust, are used to create a building material such as concrete, but stronger. It is unique in the way it absorbs carbon dioxide during the drying and hardening phase. And that's what makes it carbon neutral.

AshCrete is a concrete alternative that uses fly ash instead of traditional cement. By using fly ash, a by-product of burning coal, 97 percent of traditional concrete components can be replaced with recycled material. Concrete is a mixture of cement, aggregates and water. Globally, concrete is one of the most widely used building materials in residential and commercial applications.

Its appeal includes the fact that the components for manufacturing it are almost universally available, as well as its strength and durability that make it a practical and desirable building material.
