Chapter 2: Portland Cement

Chapter 2: Portland Cement Types of Portland Cement Portland cement is a hydraulic cement capable of setting, hardening and remains stable under water. It is composed of calcium silicates and some amount of gypsum. OPC is the most commonly produced and used cement. The name “Portland” was derived from lime stone called “Portland stone” quarried in Dorset, UK, due to its resemblance ...

Cement Types - Portland Cement Association

In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder. The heating that occurs in the kiln transforms the raw materials into new chemical compounds. Therefore, the chemical composition of the cement is defined by the ...

Portland cement production is already responsible for over 8% of global carbon emissions 1, yet its production is set to increase by 25% by 2050 1 - a period in which rapid global decarbonisation is urgently required. Current methods of reducing the amount of embodied carbon in concrete – replacing cement with slag and fly ash – are inadequate due to their small and declining supply, but ...
