Cement - Wikipedia

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.

Ministry of Energy and Energy Industries Quarrying

It is noted that quarrying activities have adversely affected the forests, wild life sanctuaries, water courses and communities. The minerals that are quarried are primarily sedimentary in origin. Blue coloured limestone and sharp sand and gravel of various grades are quarried in the Northern Range for use in the construction industry.
