Concrete is the second most used substance in the global economy, after water – and one of the world’s biggest single sources of greenhouse gas emissions. The chemical process by which cement, the key ingredient of concrete, is created results in large quantities of carbon dioxide. The UN ...

In the development of low-emission concretes the focus has been on the reduction of carbon footprint by using supplementary cementitious materials (SCMs). However, the resistance against chloride ingress may vary considerably among the different types of SCM concretes. For concrete structures exposed ...

Climate norms haveimposed the European Union to reduce Greenhouse Gas emissions by 55% by 2023and forthe whole of the EU to become carbon neutral by 2050.These objectives are legally binding: individual states are, in fact, working to achieve these objectives within the specified timeframes....
Across the globe, concrete is known to be the most extensively manufactured material. It is also one of the biggest contributors to greenhouse gas emissions, making up a minimum of 8% of global energy-related carbon dioxide emissions. Maria Konsta-Gdoutos. Image Credit: University of Texas at ...
FA can be used as a valuable resource in concrete, greenhouse gas emissions, and embodied energy. HVFA is an approach to maximize the FA content in concrete and minimize OPC use for a similar level of mechanical properties. In contrast, Dunstan et al. (1992) referred to any concrete ...

PURPOSE: Blended cements use waste products to replace Portland cement, the main contributor to COemissions in concrete manufacture. Using blended cements reduces the embodied greenhouse gas emissions; however, little attention has been paid to the reduction in COcapture (carbonation) and durability. ...
