Dolomite powder, M-sand and Compressive strength, split tensile strength and flexural strength I. INTRODUCTION Concrete should not be confused with cement because the term, cement refers only to the dry powder substance used to bind the aggregate materials of concrete. Therefore, Concrete is a construction material composed of cement (commonly.Dolomite - Dolomite - Uses Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces. The use of dolostone as a flux has increased, especially since environmental contamination has become a widely heeded.

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.Dosage of Dolomite along with controlled concrete as 1 group having 9 cubes. The cubes of compressive quality was evaluated at the period of 7th and 28th days. 6. Results And Discussions From the experimental investigation the following results are obtained for concrete by addition of Dolomite powder to concrete.

That the addition of dolomite in powder form to cement performs a comparable compressive strength to Portland-limestone cement [1,2]. over, similar to limestone, dolomite may be involved in hydration of cement, resulting in the formation of carboaluminates and the stabilization of ettringite. Besides, Mg released from dolomite is considered.In top layer cement, dolomite powder and pigment are used and in bottom layer cement, fine aggregate, semi grit, quarry dust is used. dolomite powder and pigment is used. Partial replacement of cement to the different percentage 0.1 , Table 6 6Compressive Strength of. Partial replacement of marble powder in cement accordingly in the range of.

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 whiteness - 95 +. In nature, considerable variations in the composition of dolomite relating to lime and magnesia percentages are found. When the percentage of CaCO3 increases by 10 or over the theoretical composition, the mineral is termed 'c alcitic dolomite', 'high-calcium dolomite' or 'lime-dolomite'.
