The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1 - Quarrying The raw material for cement manufacture is a rock mixture which is about 80% limestone (which is rich in CaCO3) and 20% clay or shale (a source of silica, alumina and Fe2O3). These are quarried and stored separately.

Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3 ), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the ...
According to the Intergovernmental Panel on Climate Change, IPCC, for every tonne of cement produced there is a one and a quarter tonnes equivalent of CO 2 released. 4.2 billion tonnes of cement multiplied by 1.25 tonnes of CO 2 per tonne of cement produced gives an eye watering 5.2 billion tonnes of CO 2 emitted from cement production in 2015.

cement and water content of a concrete mixture—while maintaining a constant water-cement ratio—can result in equal or reduced compressive strength, and can increase slump loss by a factor of two or more (Whiting and Dziedzic 1992). Water reducers decrease, increase, or have no effect on bleeding, depending on the chemical composition of the ...
