Alkaline cement, often referred to as alkaline-activated cement, is a type of cementitious material that is characterized by the use of an alkaline environment to facilitate the chemical reaction that sets and hardens the binder. Unlike traditional Portland cement, which relies on the hydration of clinker minerals, alkaline cement uses industrial by-products such as slag, fly ash, or other pozzolans, activated by alkaline solutions like sodium or potassium hydroxide or silicates. This form of cement is renowned for its low carbon footprint, utilizing waste materials effectively, and providing enhanced durability, making it particularly suitable for use in severe environmental conditions where traditional cement may fail.
