Al Rafidain - Ordinary Portland Cement (OPC) CEM I (42.5 R)

Portland cement was the first cement to be produced all over the world, and the most popular one. It was named “Portland” because of the similarity in shape and color with the cement material and limestone, which exists in Portland Island, in England. It is defined as the hydraulic bonding grey fine powder, which is the result of crushing a dry mix, made of clinker and gypsum. Adding and mixing water to it hardens this grey fine powder, which is known as the initial setting, and this is what makes it resistant to water and able to bear compressive stresses.
