You can remove dried cement from an aluminum window by using a soft scrubbing pad, water, and a cleanser. Scrub in the direction of the grain. Repeat until the cement is gone. If this does not work, you can try denatured alcohol.
Basic chemical elements in Portland Cement are calcium, silicon, aluminum and iron oxide.....
Basically there are four essential elements used to make cement. They are Calcium, Silicon, Aluminum and Iron.
The chemical composition of cement is Calcium oxide, Silicon dioxide, Aluminum oxide, Iron oxide, water, and sulfate. They mix, crush, and blend together limestone, silica (sand and other materials), aluminum, iron, and gypsum.

Bauxite is used in cement, chemicals, face makeup, soda cans, dishwashers, siding for houses, and other aluminum products. It is recycled so that it can be used over again.
Hope this helps... Look for foaming agents in the article. I have never tried this, but I purchased 1kg of aluminum oxide to do a test. The article reads aluminum powder. I am not sure if there is a distinction between powder and oxide? http://www.geocities.com/flyingconcrete/manual2.htm

Limestone has greater strength and better bonding capacity.Limestome is crushed in to fine particles in the preparation of cementLimestone is the major constituent in cement of about 60-67%.
there are aluminum pools, steel pools if they are above ground and they also have cement in ground pools that they build in your yard.
Compounds that form when an element such as aluminum or iron combines chemically with oxygen are called oxides. Oxide minerals are used to make products such as abrasives, toothpaste, cement, and paint.
