This method deploys the bacterial activity that decomposes urea into carbonate and ammonium ions. The carbonate ions (CO 3 2−) combine with calcium ions (Ca 2+) to form calcium carbonate (CaCO 3) and the precipitated calcium carbonate can cement sand grains. The mineralogy of the precipitated calcium carbonate mostly proves to be calcite.

Enzyme-induced carbonate precipitation (EICP) is a promising technique for soil reinforcement. To select a suitable calcium source and a suitable solution amount for aeolian sand stabilization using EICP, specimens treated with different solution amounts (1.5, 2, 2.5, 3, and 3.5 L/m 2).Surface strength, crust thickness, calcium carbonate content (CCC) and …
Balanced chemical equation of CaCO 3 and HCl reaction with physical states CaCO 3(s) + 2HCl (aq) → CaCl 2(aq) + CO 2(g) + H 2 O (l). Calcium carbonate is not soluble in water and exists as white precipitate in the water. When aqueous hydrochloric acid is added, you can observe air bubbles are generated and calcium chloride, carbon dioxide and water are formed.
Potassium carbonate (K 2 CO 3) was then injected into sand with calcium hydroxide (Ca(OH) 2 as a calcium source to precipitate CaCO 3 and regenerate KOH. Batch and continuous flow precipitation methods produced a poor distribution of CaCO 3, with more CaCO 3 precipitated on top, resulting in unconfined compressive strength (UCS) of 6.9 to 19.6 ...
PDF | On Mar 1, 2021, Ning-Jun Jiang published Discussion of "About calcium carbonate precipitation on sand biocementation" by Rafaela Cardoso, Rita Pedreira, Sofia O.D. Duarte, and Gabriel A ...
A novel calcium carbonate cement system that mimics the naturally occurring mineralization process of carbon dioxide to biogenic or geologic calcium carbonate deposits was developed utilizing carbon dioxide-containing flue gas and high-calcium industrial solid waste as raw materials. The calcium carbonate cement reaction is based on the polymorphic …

It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris.
