Cementitious materials refer to materials that are composed of or contain cement as one of their key components. These materials are widely used in construction for their ability to harden and set into durable structures when mixed with water. Research in the field of cementitious materials focuses on improving the performance, durability, and sustainability of these materials. This may involve studying the chemistry and microstructure of cementitious materials, developing new types of cement or additives to enhance properties such as strength or workability, and investigating ways to reduce the carbon footprint of cement production. Overall, research in the cementitious materials field aims to advance the understanding and application of these materials in construction to create more sustainable and resilient infrastructure.
