Portland cement, the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-speciality grout, was developed in England in the mid 19th century, and usually originates from limestone. James Frost produced what he called "British cement" in a similar manner around the same time, but did not obtain a patent until 1822.Variation of Feed Chemical Composition and Its Effect on,estimate quantities of the raw materials (limestone, clay, iron ore,.. ) required to prepare kiln feed.
