Portland cement manufacturing process and ratings of equipments

manufacturing portland cement. The LCI of portland cement is the basis of the LCI of concrete, concrete products, and concrete structures. These LCIs are used in turn to conduct life cycle assessments of concrete structures and other structures containing concrete. The scope is defined by the functional unit of portland cement and the system
