The calcium carbonate content of the eggshell is 94%, and the MICP application effect was good. Cheng used seawater as a calcium source of MICP, and the strength of the sand column increased significantly after repeated treatments with seawater. This research show that energy consumption and carbon emissions can be significantly …

Searching for alternative materials to reduce the extraction of natural resources is key to a more sustainable world and relevant to construction and infrastructure projects in which large amounts of materials are used. Eggshell is a solid waste that is rich in calcium carbonate and can potentially replace limestone for lime production.

The chemical elements found in calcium carbonate are widely distributed. Calcium (Ca) is the fifth most common element in the Earth's crust (after oxygen, silicon, aluminum and iron) and had been extracted from early igneous rocks by the combined effects of erosion by the weather and corrosion by acidic gases (Oates, 1998).

2.1 Extraction The raw materials used in cement manufacture are extracted in large quarries, typically with outputs of up to, or over, 2.5 million tonnes per year. Typically about 1.65 tonnes of limestone (1.5 to 1.8 tonnes) and 0.4 tonnes of clay are quarried for each tonne of cement produced.

The purity of the calcium carbonate obtained with the present method is much higher (>95%) than the one obtained by the direct bubbling method (6.5%). The overall conversion of calcium in the feed cement to calcium carbonate was much higher (10.1%) for the present method, which is much higher than the one for the direct bubbling …

Wollastonite is a natural silicate mineral that can be used as an agricultural soil amendment. Once in the soil, this mineral undergoes weathering and carbonation reactions, and, under certain soil and field crop conditions, our previous work has shown that this practice leads to accumulation of inorganic carbon (calcium carbonate). Mineral …

Limestone is one of the key minerals used in cement making. Limestone is a sedimentary rock composed mostly of the calcium carbonate (CaCO 3) and, according to the Mineral Education Coalition, comprises about 15% of the Earth's sedimentary crust. Surface mining is the general excavation method. There are a few underground …

The surface ocean is already 4–5 times supersaturated with respect to calcium carbonate. Therefore, it may be intuitive to expect carbonate minerals to precipitate if dissolved Ca 2+ and CO 3 2 − concentrations were to increase, which would reverse the effect of ocean (effectively the reverse of Equation (2)).However, the …
