The cement kiln

In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.

Calcium silica hydrates, or CSH, are the key to cement's solidity. As they form, they combine, developing tight bonds that lend strength to the material. These connections have a surprising byproduct — they make cement incredibly porous. Within the spaces between the bonds of CSH, tiny pores develop — on the scale of 3 nanometers.
