Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding. Magnesium hydroxide forms in the presence of water (MgO + H 2 O → Mg(OH) 2), but it can be reversed by heating it ...
Magnesium oxide is a substance used in sports, medicine and the food industry. Athletes and climbers handle their hands to prevent slipping. Doctors and cosmetologists appreciate magnesium oxide for anti-inflammatory and anti-bactericidal action. It is also present in some of our products as a food additive E530. Is it dangerous?

Normally, magnesium oxide (MgO) is considered to be an undesirable constituent in cement. However, as Chinese dam engineers accidentally discovered, it can help minimize cracking in mass concrete if it's processed under the correct conditions and used in the correct proportions.
Portland cement, is also introducing magnesium oxide, first as a non-toxic accelerant and also as a non-toxic additive. "Aquacast" is one magnesium oxide product being marketed by US Gypsum. Grancrete, a spray-on structural cement, has been developed by scientists at Argonne

The consistency of our Magnesium oxide guarantees a reliable cement production. ... Magnesium oxide and hydroxide are used in the production of fuel additives to prevent low and high temperature corrosion by capturing and neutralizing vanadium and sulfur compounds in the combustion process.
Magnesium oxide-based shrinkage-compensating concrete (MgO concrete) is concrete with an additive of lightly burnt MgO powder. When MgO hydration takes place, the final product is magnesium hydroxide, Mg(OH) 2. Because Mg(OH) 2 has a larger volume than its constituents, MgO concrete is expansive. Concrete made with more typical expansive
Magnesium Oxide is the oxide salt of magnesium with antacid, laxative and vascular smooth muscle relaxant activities. Magnesium combines with water to form magnesium hydroxide which reacts chemically to neutralize or buffer existing quantities of stomach acid; stomach-content and intra-esophageal pH rise, resulting in a decrease in pepsin activity. This agent's laxative effect is the result ...
Here is some more information about MgO cement. It's also commonly known as Chinacrete. The following page has some interesting information on three different formulations, and is from a manufacturer of the Magnesium Oxide. They don't make the concrete mix. It looks like the Magnesium Oxide - Phosphate mix is the stuff I'm looking for.
Magnesium Oxide [STARMAG ®] "STARMAG" is Konoshima's light burned Magnesium oxide produced from sea water. We can offer various products for diverse applications. STARMAG #150.
