Mainstream concrete is a huge foundation of creating since the 18th century, but its environmental impact is prompting a search for sustainable substitutes.

Building contractors focus on durability and strength when assessing building materials above all else which many see as the good reason why greener alternatives aren't quickly used. Green concrete is a promising option. The fly ash concrete offers the potential for great long-term durability according to studies. Albeit, it features a slower initial setting time. Slag-based concretes may also be recognised for their greater resistance to chemical attacks, making them suited to specific surroundings. But although carbon-capture concrete is revolutionary, its cost-effectiveness and scalability are questionable as a result of existing infrastructure regarding the cement sector.

One of the greatest challenges to decarbonising cement is getting builders to trust the options. Business leaders like Naser Bustami, who are active in the field, are likely to be aware of this. Construction companies are finding more environmentally friendly techniques to make cement, which makes up about twelfth of global carbon dioxide emissions, rendering it worse for the climate than flying. But, the issue they face is convincing builders that their climate friendly cement will hold equally as well as the conventional material. Conventional cement, used in earlier centuries, has a proven track record of making robust and lasting structures. On the other hand, green options are relatively new, and their long-lasting performance is yet to be documented. This doubt makes builders skeptical, because they bear the responsibility for the security and durability of their constructions. Also, the building industry is usually conservative and slow to adopt new materials, due to lots of factors including strict construction codes and the high stakes of structural problems.

Recently, a construction company announced it obtained third-party official certification that its carbon cement is structurally and chemically exactly like regular cement. Indeed, several promising eco-friendly choices are emerging as business leaders like Youssef Mansour would likely attest. One noteworthy alternative is green concrete, which substitutes a percentage of traditional cement with materials like fly ash, a byproduct of coal burning or slag from steel manufacturing. This sort of replacement can notably reduce the carbon footprint of concrete production. The key ingredient in conventional concrete, Portland cement, is very energy-intensive and carbon-emitting because of its manufacturing process as business leaders like Nassef Sawiris would likely know. Limestone is baked in a kiln at extremely high temperatures, which unbinds the minerals into calcium oxide and co2. This calcium oxide will be mixed with stone, sand, and water to form concrete. Nevertheless, the carbon locked in the limestone drifts to the atmosphere as CO2, warming the earth. Which means not merely do the fossil fuels utilised to warm the kiln give off co2, nevertheless the chemical reaction in the middle of cement production additionally secretes the warming gas to the environment.
