Dolomite, also known as " dolostone " and " dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg (CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very …
Once you crush this mineral, you have "lime powder.". Dolomite powder is high in calcium and magnesium, giving plants valuable nutrients to grow healthy and strong. This garden lime powder can also raise the pH of the soil. Many experienced gardeners use dolomite to help balance overly acidic soil.

The second mix corresponds to high-performance self-compacting concrete (water-cement ratio 0.56) and dolomite by-product replacing 40% of aggregate. Silica fume was used in this case …
One group of six dense calcitic dolomites was examined and tested during an aggregate survey made for a dam in ia. Four of the six were quite pure calcitic dolomites. One contained some cherty and some sandy dolomite as well. One was argillaceous dolomite, but the clay was not identified. All had less than 1 pct absorption.

Ok – now on to the different types of lime. This is REALLY important since there are a variety of different materials called "lime". You want your lime to be CaCO3 – 95% or higher. One exception is 'dolomitic lime' which basically has a 50:50 ratio of CaCO3 and MgCO3 – it is ok as well. You definitely DO NOT want 'hyrdrated lime ...
Dolomitization can completely alter a limestone into a dolomite or partially alter the rock. Dolomite is slightly harder than limestone. Dolomite has aMohs hardness of 3.5 to 4 and limestone (composed of the mineral calcite) has a hardness of 3. concrete. Most of the properties of concrete depend on cement.
