Dolomite: A sedimentary rock known as dolostone or ...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 magnesiumrich groundwater. Dolomite and limestone are very similar rocks.

Evaluation Of Mechanical And Durability Properties Of ..., et al (2012) (1)evaluated the bond strength of self compacting concrete mixes containing dolomite powder. Either silica flume or fly ash was used along with dolomite powder to increase the bond strength considerably. The result showed that the bond strength increased as the replacement of Portland cement with dolomite powder increased.
