what is a clinker used in cement production

Cement Industry OverviewData on Clinker and Cement Production

US cement production is widely dispersed with the operation of 107 cement plants in 36 stat The top five companies collectively operate 496 percent of US clinker capacity with the largest company representing 142 percent of all domestic clinker capacity An estimated 767 percent of US clinker capacity is owned by companies headquartered outside of the USHence it is a virtual cement production under the assumption that all clinker produced in a plant is consumed for cement production in the same plant and applying the real plant specific clinker/cement factor is a cement production value which is determined from clinker produced on site applying the plant specific clinker/cement factor Hence it is a virtual cement production under the
