Hence maintaining 30% of quarry dust, dolomite powder is incorporated to replace cement at 0%, 10%, 20%, 30%, 40% & 50% respectively. Cement is substituted with dolomite from 0% to 20% at an interval of 5% and the results are tabulated. The preliminary properties of cement, fine aggregate and coarse aggregate are studied. The cement

dolomite_

dolomite /ˈdɒləˌmaɪt/. 1.N a white mineral often tinted by impurities, found in sedimentary rocks and veins. It is used in the manufacture of cement and as a building stone (marble). Composition: calcium magnesium carbonate. Formula: CaMg (CO3)2.


that the addition of dolomite in powder form to cement performs a comparable compressive strength to Portland-limestone cement [1,2]. Moreover, 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 ...

The studies of hydration process in the mixtures of cement with limestone powder, dolomite powder and limestone – dolomite additive were reported by Nocuń-Wczelik et al. [6]. In the pastes hydrating with fine grained dolomite powder the crystallization of products is accelerated and as a consequence the strength development is improved.


Replacement 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 5.84% and 2.73% respectively.
