Cement can be defined as the bonding material having cohesive & adhesive properties which makes it capable to unite the different construction materials and form the compacted assembly. Ordinary/Normal Portland cement is one of the most widely used type of Portland Cement. The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in
of white cement depends on both the raw materials and the manufacturing process. Metal oxides (iron, manganese, and others) that are present in the finished material influence its whiteness and undertone, making it imperative to use carefully selected raw materials (See Figure 1). Depending on the intended use or application, white
Materials used to produce portland cement. Q. What are the raw materials used in the manufacture of portland cement? A. The two principal materials from which portland cement is made are a material of high lime content, such as limestone, chalk, shells, or marl, and a material of high silica and alumina content such as clay, shale, or blast-furnace slag.
