Cement acts as a glue that, when mixed with water, secures stone, gravel, and sand to create concrete. Although cement makes up only about 10% of the volume in concrete, it is responsible for as much as 90% of the carbon dioxide emissions associated with the material.Concrete stands out as the most vital and cost-effective construction material. It’s the most widely used material globally for compelling reasons: its durability, longevity, and resistance to extreme conditions such as weather extremes, fire, moisture, and mold. Not only is concrete fully recyclable, but it also absorbs carbon dioxide over time.In many cases, concrete is the sole material that satisfies the stringent standards for quality and durability in construction. Looking ahead, concrete will continue to be indispensable in forging strong and sustainable communities.Concrete with a lower climate impact, made with alternative binders, is called low-carbon concrete.*The amount of added alternative binders depends on the type of construction and exposure class.
