G. Habert, in Eco-efficient Construction and Building Materials, 2014 10.1 Introduction. Cement production has undergone tremendous developments since its beginnings some 2,000 years ago. While the use of cement in concrete has a very long history (Malinowsky, 1991), the industrial production of cements started in the middle of the 19 th century, first with shaft kilns, which were later ...

cement - cement - The major cements: composition and properties: Portland cement is made up of four main compounds: tricalcium silicate (3CaO · SiO2), dicalcium silicate (2CaO · SiO2), tricalcium aluminate (3CaO · Al2O3), and a tetra-calcium aluminoferrite (4CaO · Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols, these compounds are designated as C3S, C2S ...

Cement manufacturing requires water for cooling heavy equipment and exhaust gases, in emission control systems such as wet scrubbers, as well as for preparing slurry in wet process kilns. Today there are still wet and dry cement kilns but the wet process technology is progressively being replaced by the more efficient dry process kilns.

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are ...

For example, cement can be replaced with Fly Ash, Silica Fume, and Wood Ash, etc. A shCrete. Fly Ash is a byproduct of combustion of coal which was previously discarded in the landfill, but is now used for manufacturing green concrete. AshCrete is a substitute for traditional concrete that heavily utilizes recycled fly ash.

Cement manufacturing is an energy-intensive process due to the high temperatures required in the kilns for clinkerization. The use of alternative fuels to replace conventional fuels, in particular coal, is a widespread practice and can contribute to improving the global warming impact and total environmental footprint of the cement industry.

The basic concept of a precalciner is, therefore, to effect as much heat transfer as possible outside the kiln. Higher rate of calcination is accomplished by introducing additional heat into the precalciner Thus, about 40 - 60 % of the total heat required is introduced into the precalciner reducing the heat requirement in the burning zone by ...
