Furthermore, dolomite powder can reduce the water-cement ratio and increase the density and porosity of concrete, which improves the durability and resistance to freeze-thaw 3319 cycles. The use of dolomite powder in concrete can also reduce the amount of cement required, which can lead to cost savings and reduced environmental impact.

The results indicate that replacement of cement with dolomite powder increases the compressive and split tensile strength and flexural strength of concrete. ... The present examinations indicate that the use of dolomite limestone as component instead of limestone is a viable solution for producing Portland dolomite limestone cement, especially ...

This study investigated the sulfate resistance of Portland-dolomite cement (PDC) cured at different temperatures. Mortars of Portland cement (PC) and PDC with different dosages of dolomite, 10, 20, 30% by weight, were cured in water at 20 °C and 60 °C for 28 days before immersed in 50 g/L Na2SO4 solution at 20 °C. In addition to monitoring the length changes of …

On the other hand, one important difference between dolomite and limestone is that the former is unstable in the alkaline environment of cement paste, and in some certain dolomitic aggregates, the dedolomitization reaction could induce deleterious expansion in concrete [22], which is also the major concern for the long-term stability of Portland-dolomite cement (PDC).

devoted to the use of local dolomite resources as filler in different concrete mixtures as well as to the application of dolomite lime in natural fiber composites.

Studies show that dolomite has been successfully utilized in various civil engineering applications. In combination with dolomite powder (3:1), fly ash has been successfully used in self-compacting concrete [6].A reduction in slump value was observed when dolomite powder was used as filler material in self-compacting concrete [7].Dolomite stone can be used …

To reduce the heavy reliance on limestone in cement manufacturing, dolomite powder is an excellent alternative. Dolomite particles enhance the early hydration process and …

Few steel plants have dispensed with the use of dolomite in blast furnaces and its use in the preparation of self-fluxing sinters is found adequate for blast-furnace charge. ... 660 thousand tonnes (7%) and Cement Industry 560 thousand tonnes (6%). Industry-wise consumption data during 2017-18 to 2019-20 are furnished in table - 3.

The utilization of dolomite quarry waste material as binder and aggregate has been studied in various studies [10,11,12].The various studies available on the fresh properties showed that the effective use of dolomite quarry wastes as cement or sand influenced the workability of concrete [].Saranya et al. [] found that geopolymer concrete's workability was decreased by …

The use of CKD in concrete and mortar samples at different proportions was investigated as a replacement for Portland cement. ... Dolomite and significant amounts of anhydrite (CaSO 4) are present in CKD. Lastly, there are also significant amounts of quartz and traces of sylvite (KCl). The amorphous component is based on an aluminosilicateglass ...

Dolomite can be used as one of the compounds in cement as it is easily crushed and then with water and dried, will solidify to a new form. Of course, to increase strength of cement, one …

Cement asphalt emulsion composites (CAEC) are gradually being valued by pavement researchers because of its environment-friendly properties. However, there are still great difficulties in producing high-performance CAEC at present. Dolomite powder (DLM) has been proved in providing promising improvement effects on cement-based materials as an …

This study investigates the use of dolomite powder as a cement substitute in some cases. Dolomite is a mineral that forms rocks and is renowned for being very wettable and dispersible. Dolomite resists deterioration well in the weather. Dolomite's superior surface hardness and density make it a desirable building material.

Use of Dolomite in Cement Industry. Dolomite is a type of mineral that consists of calcium magnesium carbonate. It is widely used in the cement industry as a source of magnesium oxide. Dolomite is also used in the production of float glass, as a fluxing agent in the production of metals, and as a fertilizer.
