  • REPLACEMENT OF CEMENT WITH DOLOMITE POWDER: AN

    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. In case of split tensile strength, the optimal replacement

  • Application of light-burnt dolomite as a mineral addition

    05/04/2019· Growth in the production of cement has led to increasing demands for mineral additions. This study was conducted to develop an alternative addition by calcining dolomite at 800°C to obtain a mixture of periclase (MgO) and calcite (CaCO 3). The light-burnt dolomite (LBD) was used to prepare blended cements. The hydration, setting time and microstructure of the cement were assessed and

  • The Effect of Dolomite Additive on Cement Hydration

    01/01/2015· The effect of dolomite on alite hydration was investigated in order to elucidate the effect of dolomite addition in cement hydration. The rate of heat evolution both in cement dolomite and alite dolomite system was taken as a starting point. Subsequently the chemical shrinkage, conductivity of liquid phase and rheological parameters of pastes were characterized. The observations of

  • Using of an Alternative Dolomite Filler in Concrete CORE

    Physical and chemical property investigation of material showed generally homogeneous mineralogical composition of waste: dolomite CaMg(CO3)2 content is not less than 92 %. Fine-graded and ordinary concrete materials were produced substituting quartz sand with dolomite waste sands. Frost resistance and compression strength of concrete specimens filled with dolomite waste are equal as for concrete filled with quartz sand

  • Effect of Dolomite Limestone Powder on the Compressive

    01/01/2013· In this case interface layer possesses good adhesion resulting in modified concrete strength and density increasing. Thus, dolomite limestone ultrafine particles act as additional crystallization grains; optimal content of dolomite limestone is 25% of cement weight. At this amount fine concrete has the best compression strength. 3.3. DTA Differential thermal analysis of the cement composition (Fig.
