The Brazilian cement industry has a long history (more than 70 years) in the production of blended cements, with a nationwide average clinker-to-cement ratio below 70%.₅ In Brazil, the most widely used SCM is currently blast furnace slag from steel mills,₆ though calcined clay and fly ash are also in the mix.
GBFS is mainly used for grinding and producing GGBFS as well as blended cements with slag. GBFS is also used as an effective replacement of natural sand / crushed sand in concrete as a fine aggregate. GGBFS enhances long-term performance and durability characteristics in concrete while reducing life-cycle and maintenance costs.
Grinding is a highly energy intensive process in the cement industry. Approximately 60 – 70 % of the total electrical ene rgy used in a cement plant is utilised for the grinding of raw materials, coal and clinker.

Granulated Blast Furnace Slag (GBFS) contains a high level of moisture, it is hard to grind and very abrasive. 2 Natural pozzolans may not be as hard to grind as GBFS but may contain high moisture levels and be abrasive. 2 Both of these materials require grinding systems designed to deal with high moisture, hardness and abrasiveness. GBFS can be utilized in the cement …

The type of cement used in concrete foundations is determined by the concentration of sulphates in the groundwater. Portland cement is manufactured by grinding limestone or chalk with clay or shale, mixing the ground materials in specified proportions and then burning the material in a kiln to a temperature of about 1400°C.
In addition to the fuel, much of the cost of portland cement manufacturing is grinding the fused clinker that comes out of the kiln to face-powder fineness, and even finer for high-early strength-developing Type III portland cement.
Concrete Cost Per Yard According to the NRMCA, concrete costs $108 per cubic yard on average. With concrete delivery and pouring, most pay $119 to $147 per cubic yard depending on the PSI of the cement. A full 10-yard truckload with delivery costs $1,169 to $1,444, which is enough to pour a 20x24 driveway.
