    For this reason the early cement industry used the "wet process" in which the raw materials are ground together with water to produce a slurry containing 20–50 water. Both Louis Vicat and James Frost used this technique in the early 19th century and it remained the only way of making rawmix for Portland cement until 1890. Process emissions can account for half or more of emissions from cement manufacture. Clinker can be produced by a number of different manufacturing processes. The "dry" process is much more energy-efficient than the "wet
