  • Calcitic vs. Dolomitic Lime What’s the Difference?

    2022-5-10 · Difference Between Dolomitic and Calcitic Lime. Calcite lime and dolomite lime are both derived from limestone, but calcite lime contains higher calcium levels. Dolomite lime contains less calcium but on the flip side contains magnesium, which is rarely present in calcitic lime. This may seem like a small difference, but it makes an impact.Calcite vs. Dolomite What's the difference? Ask Difference,2021-12-18 · Calcite noun.

Fig. 1 illustrates the Raman spectra of calcite (Cal) and dolomite (Dol). Some variations in both the band positions

  • Difference Between Calcite and Dolomite

    2011-11-10 · Dolomite differs from calcite because of the presence of magnesium. • Calcite reacts quickly with acids and produce carbon dioxide bubbles. But dolomite is weakly reacts with acids producing bubbles very slowly. When hot acids or powdered dolomite is used they may react quickly. • Dolomite is slightly harder and denser than calcite.Understanding the hydration of dolomite in cementitious ,2018-6-1 · Therefore, it is not uncommon to observe dolomite coexisting with calcite. The presence of dolomite renders limestone unsuitable for the production of clinker, as the dolomite will decompose in the rotary kiln to form periclase (MgO), which forms brucite (Mg(OH) 2) during the later stages of cement hydration. The formation of brucite from

  • POROSITY LOGGING

    1999-2-9 · (quartz), if a limestone, the matrix density is 2.71 gm/cc (calcite); if a dolomite, then the matrix density is about 2.87gm/cc. The density log is scaled as bulk density in grams per cubic centimeter. If a “density porosity log” is displayed, then it will be an apparent porosity keyed to a specific mineral, usually calcite, inKGS--Geological Log Analysis--The Photoelectric Factor ,However, this difference is caused by calcite cement within the sandstone. While the upper part of this section matches the expectations for a dolomite response, the lower part shows another component.
