In general, precipitated calcium carbonate (PCC) is used as a mineral filler in paper industries; while natural calcite (CaCO3) ore is also suitable for industrial use if it is a finely ground high-grade material. Naturally, calcite is found in the form of high- or low-grade ores and it is one of the most widely distributed industrial minerals on the earth's …

Calcium carbonate binders were prepared via carbonating the paste specimens cast with steel slag alone or the steel slag blends incorporating 20% of Portland cement (PC) under CO 2 curing (0.1 MPa gas pressure) for up to 14 d. The carbonate products, mechanical strengths, and microstructures were quantitatively …

Abstract. Discreet nano-sized precipitated calcium carbonate was prepared by a simple solution mixing process, in which sodium carbonate solution was injected into calcium chloride solution containing calcium hydroxide. The morphology, size, and structure of the as-prepared precipitated calcium carbonate and intermediate products …

The traditional treatment method is to soak the recycled aggregates in a mixture of urease-producing bacteria, urea and calcium source, and the generated calcium carbonate can cover the surface and the pores of the recycled aggregates through the effects of gravity and adsorption (Wang et al., 2017; Feng et al., 2020; Zhan et al., 2020; …

A molecular modified PCE-type GA was self-synthesized, and the grindability concerning grinding duration and particle size distribution of ground cement was evaluated. Setting time, flowability, hydration heat, mechanical properties and microstructure of the ground cement were also investigated. The results show that: PCE-type GA is effective …

Calcium carbonate occurs naturally in many forms such as Chalk, Limestone, Marble and sea shells. It can be found worldwide and ranges in color (because of impurities) from white to gray to yellow. A white pigment of calcium carbonate is prepared by grinding limestone, chalk or shells with water then using levigation to …

For example, one option is to fine-grind the dry slag (here 6 h of dry-grinding +20 h of reaction time was required) and then use a 1-mol/L mild solvent. Or, as a more feasible processing option, we can use extractive grinding (only 20 min process time here obtained) with the mild solvent and more coarse slag in order to reach the same outcome.
