· This paper aims to investigate drying shrinkage, strength and microstructure of alkali-activated high-calcium fly ash (AAHF) paste by using FGD-gypsum (FGD) and dolomite (DLM) as expansive additives. The 10 M sodium hydroxide combined with sodium silicate solutions were used as alkaline activator for all mixes.

Adding Dolomite Lime To Adjust Soil pH If your goal is to change the pH of the soil, calculate how much you need ahead of time. Generally, if the soil has a pH of 5.5 and you want to raise it by one point, getting it closer to 6.5, you will add 5 pounds of dolomite lime for every 100 square feet of space.
· The problems of enrichment of dolomite, which is used in the preparation of glass batch, are examined. A design of a production line for processing lump dolomite that includes equipment for drying, crushing, and three-step separation of the comminuted material is presented. It is shown that additional reduction of the amount of the dusty fraction of dolomite present in the finished product is ...
· Process two: Milling and classifying dolomite rock. Milling: The crushed dolomite rock is transported from the bottom up to the silo by a bucket elevator and then sent to the Raymond mill for grinding by an electromagnetic vibrating feeder; Classifying: Dolomite is ground to 325-1250 mesh to produce dolomite powder.
· drying method were similar except for density because the spray-dried samples showed values lower than those of traditionally dried samples. Conclusions: the results indicate that the tested spray drying conditions are suitable for drying of calcium and magnesium citrate from dolomite
Dolomite Refractory: Dolomite bricks are made up of MgO 25-45%, CaO 35-65%, and other materials. They have high refractoriness, Thermal stability at high temperature and slag resistance. They are more porous, more shrinkage softness and less strong. They can be used up to 2300 o C without load and up to 1650 o C with the load.
In addition to dolomite, traces of low-Mg calcite with MgCO 3 contents of ca. 5.25 mol% (d 104 = 3.019 Å) were also detected in the annealed biotic protodolomite samples either heated at 200 °C or 300 °C and in the 60 °C-synthesized abiotic protodolomite sample heated at 300 °C (Figs. 2b, 3a and Fig. S2). The biotic protodolomite sample heated at 200 °C was selected to further observe ...
· Low-cost porous calcined dolomite microspheres were prepared by simple spray drying and subsequent calcination. Effects of calcination temperature on phase evolution and adsorption properties of were investigated systematically. Results showed that microspheres treated at 400 °C kept mainly calcium carbonate (CaMg (CO3)) phase with some small pores, showing better removal efficiency for …

The invention discloses a preparation method for dolomite refractory bricks, and relates to the technical field of refractory material preparation. The preparation method comprises the steps that the dolomite refractory bricks are prepared from, by weight, 60-80 parts of dolomite, 10-20 parts of pyrophyllite powder, 20-35 parts of magnesia and 8-20 parts of paper pulp; the dolomite is crushed ...
Notes. Dolomite as a ceramic material is a uniform calcium magnesium carbonate. In ceramic glazes it is used as a source of magnesia and calcia. Other than talc, dolomite is the principle source of MgO in high temperature raw glazes. 'Dolomite matte' stoneware glazes, for example, are highly prized for their pleasant 'silky' surface texture. Dolomite by itself is refractory, but when combined ...
