Sustainable Construction Materials for Constriction

What is it about?

New, sustainable low-Carbon Dioxide (CO2) construction materials must be developed for the global building sector to decrease its environmental impact. During the last several decades, Alkali-activated Materials (AAMs) is a Portland cement-free form, have been intensively researched as a potential alternative for ordinary Portland cement concrete (OPCC), with the objective of lowering CO2 emissions while repurposing a large volume of industrial waste by-products. The suitability of using AAMs made up of industrial waste by-products such as blast furnace slag (BFS), calcined clay (metakaolin), and fly ash (FA) was investigated in this study utilizing a performance-based approach that was unaffected by binder chemistry, history, or environmental effect, Binder paste microstructural assessment and influence on engineering effectiveness, including fresh and hardened characteristics of these materials, In the Viewpoints area, we analyze specific premature phase and long-phase performance of AAMs, as well as Upcoming scientific breakthroughs are also discussed in the Viewpoints section.

Why is it important?

Alkali-activated materials (AAMs) have become an alternative to Portland cement-based binders that are low in CO2 during construction. AAMs can also be used in a wide range of high added value applications, including the solidification and stabilization of hazardous wastes, the production of ceramic-like products, advanced composites, and environmental applications, to mention a few. AAMs may also be made from a variety of large-scale industrial leftovers and mineral wastes. In order to combat climate change and advance a circular economy, AAMs are crucial.
