How cement is made. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken …

In the cement industry, however, this link is weak. The industry's record of value creation is spotty, with ROIC levels roughly equal to the cost of capital, at around 9 percent. Behind the lackluster ROIC, two drivers stand out: high goodwill (seen in the low tangible capital ratio) and inadequate capital efficiency. Call it bad timing.
