    Nov 23, 2019 3.1 Effects of Portland cement on setting time of MOS cement prepared by light-burned dolomite Setting time is one of the important properties of cement which can directly reflect the hardening rate of cement. Figure 1 shows that the setting time of MOS cement prepared by light-burned dolomite with different amounts of Portland cement.The purpose of this work is to describe the effect of fine ground dolomite on important physical and mechanical properties of concrete. Dolomite powder has some similar characteristics of cement. The replacement percentages tried were 0 , 5 , 10 , 15 and 20 by weight of cement. The compressive, split tensile and flexural strengths of concrete with dolomite.

    In this paper, the effects of different stone powder content (5 , 10 , 15 , 20 , 25 ) of dolomite manufactured sand on the workability and mechanical properties of cement were studied. The influence of stone powder content on the hydration products and microstructure of cement were studied by XRD, SEM. The results show that the workability and mechanical.Aggregate (in Iowa) and cement paste have been reported to result in reaction rims with increased silica coocentiatirais at the outer mar^ns of the aggregate (Bisque Lemish, 1958).

    Cement And Its Effect To The Environment: A Case Study

    Oct 17, 2018 In addition, free lime has shown a harmful effect on the stability, physical properties and hardening of cement when exceeding a certain content . For example, with the loss of ignition within 25 07 at the temperature of 850 C after passing 1 5 h, MOS cement could not be formed because the reaction was too intense and hardening took place.Cement production, one of the reasons for such deformations in hardened magnesium cement is high content of calcium carbonate in the source rock [15]. According to GOST 1216-87, the calcium oxide admixture which is synthesized while decomposition of dolomite and calcite is considered adverse for magnesium cement and shall be limited up to 5 [16].
