Concrete is a composite material that is made by mixing cement together with a range of different aggregates. It can be made with ballast, gravel, sand and more. The amount of concrete used in the world is staggering, with it being the second-most-used substance in the world. The first? Water.
Because of its high usage, there is an emphasis on recycling concrete. So read on to find out more about recycling concrete to use as an aggregate.
What is Recycled Concrete Aggregate?
When concrete is recycled, it can be reused as crushed concrete aggregate, made up of the asphalt debris that is wasted during construction projects. This could include concrete from pavements, foundations, old structures and more. The concrete can then be reused in a variety of applications, such as driveways and garden beds.
Crushed concrete is made by using industrial equipment to break up old concrete, then it is run through a secondary impactor to crush it to a smaller size. It is then screened to ensure any dirt or foreign objects are removed, before being separated into different sizes for different applications.
Here are a few reasons it is beneficial to use crushed concrete aggregate in your projects.
Helps The Environment
The production of cement produces a staggeringly large amount of greenhouse gas emissions, which amounts to nearly 8% of emissions worldwide. Concrete is not biodegradable, so after it is used will just end up sitting in landfills, not decomposing. Instead, new concrete is produced, adding to the emissions and creating more non-biodegradable material. By recycling concrete instead, it can help reduce landfill crowding and stop the construction of more concrete, saving the resources used to do so and not contributing to harming the environment.
Versatile
Old concrete can be crushed down to specific sizes, so can be used for a wide variety of applications depending on the project. Large pieces of concrete can be used to control erosion on shorelines, acting as a visually appealing breakwater. More common applications include walkways and constructing raised garden beds, leading to improved drainage and warmer soil in your garden. It can also be used to form a stable base on parking lots and roads. Crushed concrete can even be reconstituted as new concrete, making it a completely renewable material.
