The dominant form of cement used worldwide is Portland cement with approximately 4 billion tonnes produced in 2014. Named in the 19th century because of its apparent visual resemblance to limestone quarried from the Isle of Portland U.K. this cement consists primarily of hydraulic calcium silicate phases which are produced in a kiln at elevated temperature to produce "clinker" which
