Abstracts: Concrete is a construction material used intensively all around the world. The principal components of concrete are Portland cement, water, aggregate, sand and chemical admixtures. The production of Portland cement requires significant amounts of energy and is an important contributor to the global warming. This paper presents a teaching experience using fly ash and other waste material to reduce the consumption of Portland cement that result in Green Concretes.
