Dolomite powder gotten by powdering the sedimentary shake shape material dolostone can be employed as a substitute fabric for cement in concrete up to specified rate. Dolomite powder has a few comparable qualities of cement. Utilizing dolomite powder in concrete can lower the fetched of concrete and may enhance the quality to a few extents.

The crushed granite screenings are 1.5–2 times finer compared to the fineness of dolomite screenings crushed for the same time. Besides, the fineness of carbonate rock powder can be easily adjusted by changing crushing time. Therefore, dolomite screenings is a very perspective raw material for producing concrete micro-aggregates.

Pour dolomite powder and introduce it into the soil before sowing (planting) or after harvesting. The optimal time for applying dolomite powder is spring (after snow melt) and late autumn. The average fertiliser application rate is 300 g/m2. Around bushes and trees, apply the fertiliser within the width of a whisk broom.

Addition of dolomite through sinter is more preferred route since CO2 of dolomite is driven out during the sintering process. In case of sintering, dolomite is crushed to -3 mm (in the range of 85 % to 90 %) in hammer crushers before mixing it in the sinter mix. In case of direct feed to blast furnace, lump dolomite (10 mm to 30 mm size) …
