In 1913, after many turns and twists, the first cement mill was installed in the Maeda district of Yawata Works and PBFSC production commenced on a full scale. At that time, the PBFSC was produced by intergrinding of Portland cement clinker purchased from Asano Cement Moji Plant, granulated blast furnace slag, and gypsum.

The GBSF temperature at the blast furnace output reaches about 1400 ÷ 1450 °C and it is cooled slowly by means of air or quickly by waterjet. The latter process is called granulation and leads to the formation of a product called granulated blast furnace slag (GBFS) and this form of slag is used in the composition of cement and concrete.

Abstract. Grindingrelated parameters of blast furnace slag cements (BFC), such as Bond grindability, specific rate of breakage and breakage distributions were determined employing separate and intergrinding modes. Strength tests were performed on mortar specimens made by BFC prepared by these modes of grinding to the same fineness.
