dolomite limestone reaction

Reaction mechanism of dolomite powder in Portland
2021-2-8 · Dolomite powder may be involved in the hydration reaction of cement forming carbonate-AFm phases, and has a similar effect on strength development as limestone additions , . Furthermore, the combination of dolomite and calcined clay in cement also yields a positive synergistic effect that leads to finer pore structure and higher mechanical ...

dolomitization | mineralogy | Britannica
dolomitization, process by which limestone is altered into dolomite; when limestone comes into contact with magnesium-rich water, the mineral dolomite, calcium and magnesium carbonate, CaMg(CO 3) 2, replaces the calcite (calcium carbonate, CaCO 3) in the rock, volume for volume.Dolomitization involves recrystallization on a large scale. The dolomite mineral grains

Flow, dissolution, and precipitation in dolomite
2017-10-4 · dissolution of dolomite is a (slow) reaction rate limited process at room temperature [Lund et al., 1973]. The main aim of the current experimental research is to understand the evolution of hydraulic conductivity and flow patterns, caused by concurrent dissolution of dolomite and precipi-tation of calcium carbonate, in porous dolomite rocks. In
