This also forms a cekent important operational step since cement needs very careful packing and storage arrangements. Hydraulic limes were favored for this, but the need for a fast set time encouraged the development of new cements. Ensuring a good yield The reliability coefficient of a kiln is calculated by comparing the number of lost time hours to the number of operating hours.
