Concrete is a construction material that has been used around the world for centuries. It is a mixture of cement, sand, gravel, and water. However, recent research has revealed concrete construction’s negative effects.
For example, it is one of the largest contributors to carbon dioxide emissions. Transportation accounts for 7 percent of concrete’s CO2 emissions.
Another major contributor to carbon emissions comes from the cement industry. Portland cement is the key ingredient in concrete. During production, liquefied carbon dioxide is injected into the concrete.
Another alternative to concrete is a composite material. A new type of composite material is four times more water-resistant than traditional concrete. This could help reduce the need for conventional concrete.
Other types of alternative materials are being researched. One is called “fiberous” concrete. Fiberous concrete is made from waste cardboard. The material does not replace the entire concrete mix, however.
While there are many different ways to substitute for conventional concrete, replacement of all concrete is unlikely. Instead, concrete repairs may be the only viable option.
The next best thing to replacing concrete is to repair existing concrete. Repairs can be done by using an attractive finish that will disguise the repair.
Some researchers are looking into replacing cement with graphene. In the meantime, alternative materials such as bamboo and calcite clays are showing promise.
If you need concrete in the future, it is important to consider other options. New materials have the potential to lower the environmental impact of construction.
