Clinker can be substituted with other cement-like materials, including waste from coal combustion and steelmaking. This can affect the cement's properties, however, so is only suitable for some end uses. The world average clinker ratio (clinker:cement) fell to 0.65 in 2014, with a large range from 0.57 in China to 0.87 in Eurasia.
