Concrete is used to create hard surfaces which contribute to surface runoff that may cause soil erosion, water pollution and flooding.
Is concrete a eco-friendly material?
Construction with concrete is: sustainable, resource-efficient and eco-friendly. Concrete is a very sustainable building material with regard to the energy consumption during its production and its characteristics during its useful life.
Does concrete cause global warming?

How Can concrete be sustainable?
He says using recycled plastic in reinforced concrete has great environmental savings. “Steel is often used as a reinforcing agent for this type of concrete, and is very energy-intensive. Using plastic to reinforce concrete instead of steel can reduce carbon dioxide production by about 50%.
How Can concrete be made environmentally friendly?
Thus, in order to make concrete more sustainable one may work along one or more of the following routes; 1) Replacing cement in concrete with larger amounts of supplementary cementing materials (SCMs) than usual, 2) Replacing cement in concrete with combinations of SCMs leading to synergic reactions enhancing strength, …
Is concrete unsustainable?
Unlike wood however, concrete is made through unsustainable practices. Wood can be torn down to be reused, but concrete cannot be salvaged and it is left where it is demolished. Steel is the newest of the three materials. Steel became a popular building material during the industrial revolution due to its durability.
