[10] concluded that the carbonization blocks could have a higher strength; laboratory tests were performed to investigate the influence of the mixing amount of reactive MgO on compressive strength, microcharacteristics, and durability of the block, and they indicated that the carbonized products of reactive MgO are mainly hydromagnesite and nesquehonite/dypingite, with the higher amount of reactive MgO, the more carbonized products.
In contrast, below 60[degrees]C, hydrated magnesium carbonate, that is, hydromagnesite ([(MgC[O.sub.3]).sub.4]xMg[(OH).sub.2]x4[H.sub.2]O) or nesquehonite (MgC[O.sub.3]x3[H.sub.2]O), has been reported to form instead of stability phase of magnesite [28, 29].
UltraCarb is a multifunctional hybrid of two minerals from a natural deposit: hydromagnesite (hydrated magnesium carbonate) and huntite (magnesium calcium carbonate).
Calcite is the predominant carbonate formed from CaO, while hydromagnesite is the predominant phase formed from MgO, regardless of NiNP addition.
Magnesite and Hydromagnesite are found visually in small outcrops within 12 km off northeastern Naein and along the Naein fault and the resulting minor faults, that is, the lands between the Serar to Soucheh farms.
Regarding [Mg.sup.2+], for which prediction error is associated with the errors of [Ca.sup.2+] and S[O.sub.4.sup.2-], it may also be removed from the soil solution due to its co-precipitation with [Ca.sup.2+] to produce magnesian calcite, or its precipitation with carbonate or silicate to produce, respectively, hydromagnesite and nesquehonite or sepiolite (Suarez 2005).
This could be attributed to brucite or hydromagnesite formation at higher curing ages, since sepiolite has a magnesium compound present in its composition.
DENIZLI, Apr 28, 2011 (TUR) -- Turkey exports untite and hydromagnesite mineral to 16 countries.
Magnesite, hydromagnesite, and gypsum precipitate under playa conditions, and latter can display a radial stellate morphology (Huene 1941).
Massive white crusts of a magnesium mineral which regularly accompany stichtite are probably hydromagnesite.
