Dolomite-based quarry-dust as a substitute for fly-ash

2019-10-20  Cement production requires kiln temperature of 1450 °C, thus it possesses high embodied energy as well as release of CO 2. A production of each ton of cement releases almost one ton of CO 2 into the atmosphere; the cement industry is responsible for about 5%–7% of man made CO 2 emissions (Malhotra, 2000, Mayer, 2009, Häfliger et al., 2017).

Dolomite and dolomitization model- a short review

2018-7-13  Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg (CO 3) 2 . The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for the dolomitic rock type is dolostone. Dolomite is an unusual carbonate mineral.

Hydration of Reactive MgO as Partial Cement Replacement

A recent quest for more sustainable cement-based construction materials has triggered the pursuit of technically viable alternatives of cement, making reactive magnesium oxide (MgO) one of the least known top contenders to reduce this sector’s environmental impact since it participates in the cement’s hydration reactions and presents enhanced carbon capture ability during its life cycle.
