  • Cement origin of supratidal dolomite, Andros Island

    In the larger pores, dolomite commonly forms an isopachous fringe and may be followed by either aragonite or highmagnesium calcite (HMC) cement Siltsized bioclasts and pellets within crusts are often lithified by dolomite cement, which may totally fill much of the interparticle porosityIt is very massive and usually there are no evidences of individual crystals forming the dolomite cement The dolomite cemented sandstones that contain the anhedral dolomite are characterized by increased intergranular porosity compared to the previous dolomite types Under cathodoluminescence, the anhedral fabric has bright orange colourDolomite cements in Cenomanian continental sandReplacement of cement with dolomite powder is found to improve the strength of concrete The maximum replacement percentage of cement with dolomite powder is found to be 5% and at this replacement level, the maximum increase in the 28th day compression and flexural strength were found to be 584% and 273% respectivelyREPLACEMENT OF CEMENT WITH DOLOMITE POWDER:

  • The Effect of Dolomite Additive on Cement Hydration

    At low percentage dolomite plays a role of cement replacement; at higher dosage – the „dilution†effect can be observed However, increasing dolomite content is accompanied by higher amount of hydration products, as a results of crystallization on the fine dolomite grains and better absorption of waterThe method of preparing portland cement from dolomite involves crushing dolomite, roasting it at 9001100°C, slaking with water into a lime suspension, its separation into heavy and light particles through settling for 12 hours with separation of light particles lime milk, thickening of the lime milk into a lime paste through settling for 2024 hours, adding clay to the lime paste, homogenisation of the obtainedMethod of preparing portland cement from dolomiteDolomite and alumina are the most popular raw materials used to fabricate aluminous cement containing magnesium aluminate (ACMA) spinelAluminous Cements Containing MA Spinel from
