Regulated set cement was invented at the Portland Cement Association (USA) in the early 1970s; however, the main development work occurred in Japan, where it is known as Jet cement. The cement is derived from a fluoride-modified Portland cement clinker and contains C 11 A 7 CaF 2 (or C 11 A 7 F ) instead of C 3 A. 37 The hydration of mixtures of C 11 A 7 F , C 3 S and CaSO 4 have been ...

The proportions of clinker in each cement type change over time, and only two sets of estimates were available: one from the WBCSD and IEA (2013), assumed to represent 2012 and later, and another from IBEF (2005), assumed to represent 2005 and earlier. The clinker ratios by cement type were interpolated linearly between these two years.
The mass of bricks and coke was to be burned until the raw materials began to vitrify. If the firing went well, as the coke fuel was consumed, clinker, a substance resembling lava, dropped to the botton of the kilns. 38 The clinker was then ground between horizontal French flourmilling buhrstones. 39 The resulting powder was cement.
