dolomite powder replacing Portland cement. Either silica fume or fly ash was used along with the dolomite powder in some mixes. Seven mixes were proportioned and cast without vibration in long beams with 10 mm and 16 mm steel dowels fixed vertically along the flowing path. The beams were then broken into discrete test specimens.
The solidified material was pulverized and passed from 75 µm sieve and then kept in a tightly contact vessel until use. Ground dolomite as commercial source of MgCO 3 was used, where the content of NaOH was added to dolomite depending on MgO and CaO%. From the chemical composition, dolomite possesses 0.475 mol of MgCO 3 and 0.590 mol of CaCO 3.
DOLOMITE. Dolomite is Carbonate of Calcium and Magnesium "Ca Mg (CO3)2". We are recognized as one of the prominent Dolomite Rock Powder Manufacturers and Suppliers in India. The Dolomite Powder is extensively used in Iron & Steel Industries due to its strength and compatibility in process of purifying Iron & Steel.

The Compressive, Split Water which was used for making concrete should have a pH tensile and Flexural strength of the specimens were found between6 ...
It is used to formulate cement and aggregate materials. It is used as suitable source of magnesia in chemical processing arena. In chemical arena, it is also used to neutralize acid. In agriculture, dolomite acts as suitable soil conditioner and ph controller. As reliable source of magnesia, this powder is used as food grade additive for livestock.
White Dolomite powder as a filler for asphalt and concrete, paints, plastics, rubber, soaps and detergent applications. For adhesive formulation. Dolomite is also used in some cement, pharmaceutical, fodder, Glass and ceramic industry as a source of magnesium. As a sintering agent in iron ore palletisation or as a flux agents in steel making.
effects of using dolomite powder as a partial replacement material to cement. The dolomite powder was replaced at 0%, 5%, 10%, 15%, 20% and 25% with cement of M20 grade. The compressive, split tensile and flexural strengths of concrete with dolomite powder were compared with those of the reference specimens.
Dolomite powder is a limestone compound that contains calcium and magnesium. The best mixtures contain 8 to 12 percent magnesium and 18 to 22 percent calcium.
As we can see, partial cement replacement with dolomite limestone powder results in compression strength increasing. Strength of samples containing 25% of dolomite limestone powder increased by 16.7% and 23.5% at 14 and 28 days age, respectively, in comparison with …
