When we think of the ancients and what "technology" they had, we realize that it must have been fairly simple and we have to take into consideration just what exactly, they had available to them at any given time, and how just everday commanalities could be used for industrial purposes. Most things were likely common sense, with necessity being the mother of invention or - adaptation.

Understanding the properties of Calcinated(or calcined) Gypsum (CG) and Calcinated Limestone (CL) is very important.

Cement; (CL) With the dry process raw materials are dried before or during grinding. The principal raw materials are Limestone, silica sand, clay, shale, oxides of chalk. Silica , aluminum and iron are added in the forms of sand, clay, shale, sea shells (medium size particles of sedimentary layers, like clay, iron oxide, Gypsum. (See previous post for a bit about gypsum)

I'll just re-post this bit about diotomaceous earth:

Diatomaceous earth (IPA: /ˌdʌɪətəˈmeɪʃəs ˈəː(r)θ/, also known as DE, diatomite, diahydro, kieselguhr, kieselgur and Celite) is a naturally occurring, soft, chalk-like sedimentary rock that is easily crumbled into a fine white to off-white powder. This powder has an abrasive feel, similar to pumice powder, and is very light, due to its high porosity. The typical chemical composition of diatomaceous earth is 86% silica, 5% sodium, 3% magnesium and 2% iron.

Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae.

A good book for information of what the AE's had available to them is Atlas of Ancient Egypt by Baines & Malek. From this tome, we find that coal was also available.
