brucite

The structures are similar to the brucite structure.

The result is a composite of brucite and limestone with mechanical strength similar to concrete.

The solid mineral form of magnesium hydroxide is known as brucite.

It has the brucite or cadmium iodide crystal structure.

The different symmetry of gibbsite and brucite is due to the different way that the layers are stacked.

Natural magnesium hydroxide exists in the form of brucite and this is used commercially as a fire retardant.

Neighboring brucite layers are stacked so that the hydroxyl groups are directly above one another (Taylor et al., 1973).

It generally occurs associated with the weathering products of magnesium containing minerals such as serpentine or brucite.

As a consequence, chlorite interlayers are cemented by brucite and cannot swell nor shrink anymore.

Because brucite is a swelling mineral, it causes a local volumetric expansion responsible for tensile stress in concrete.

Amakinite is a semi transparent yellow-green mineral belonging to the Brucite group that was discovered in 1962.

Gibbsite's structure is closely related to the structure of brucite, Mg(OH).

Hydrated metamorphic rock assemblages are dominated by the minerals chlorite, serpentine-antigorite, brucite.

Reaction 1c describes the hydration of olivine with water only to yield serpentine and Mg(OH) (brucite).

Although magnesium is found in over 60 minerals, only dolomite, magnesite, brucite, carnallite, talc, and olivine are of commercial importance.

Associated minerals include brucite, hydromagnesite, pyroaurite, chrysotile, aragonite, calcite, dolomite and magnesite.

Periclase, when hydrated, forms brucite (Mg(O H)), a common product of serpentinite metamorphic reactions.

The reaction of magnesium carbonate with the free alkali hydroxides present in the cement porewater also leads to the formation of expansive brucite.

Associated minerals include rutile, spinel, clinohumite, perovskite, diopside, serpentine, forsterite, brucite, hydrotalcite, chlorite and calcite.

In between brucite layers are inter layers containing CO ions and HO molecules (Taylor et al., 1973).

Magnesium hydroxide (brucite) is insoluble in water so it can be filtered out, and reacted with hydrochloric acid to obtain concentrated magnesium chloride.

Petrologists refer to rocks composed mostly of serpentine minerals and minor amounts of talc, chlorite, magnetite, and brucite as serpentinites.

It occurs in association with apophyllite, natrolite, thaumasite, merwinite, spurrite, gehlenite, ettringite, portlandite, hillebrandite, foshagite, brucite and calcite.

Oxygen atoms are accommodated in a single set of sites distributed close to the axes that pass through the hydroxyl ions of adjacent brucite layers (Taylor et al., 1973).

Alkali from the cement might react with the dolomite crystals present in the aggregate inducing the production of brucite, (MgOH), and calcite (CaCO).
