In the Eq. (1), the reaction free enthalpy change for mineral carbonation is negative. Accordingly, CO 2 sequestration process is a spontaneous endothermic reaction. Fig. 1 shows the standard molar free energy of formation for mineral carbonate is 60–180 kJ/mol, which lower than that of CO 2.Hence, the most environmentally benign and stable form of carbon …
"construction minerals" includes stones, gravel, sands, soils, clay, volcanic ash, volcanic cinder and any other minerals used for the construction of buildings, roads, dams, aerodromes and landscaping or similar works, and such other minerals as the Cabinet Secretary may from time to time declare to be construction minerals, by notice ...
For example, Asaoka et al. (2021) synthesized coal fly ash-blast furnace cement composite doped with lanthanum (La-FACC) for the removal of phosphate in water, and the adsorption capacity was up to 24.9 mg P g −1. Ayoob et al. (2008) studied alumina cement granules (ALC) to remove low-concentration fluoride.

There are also some metal oxides with very small amounts found in PG samples, such as Al 2 O 3 (0.7 wt%), Fe 2 O 3 (0.6 wt%), and BaO (0.1 wt%). They could be preserved in the PG as the form of cation-substitution of the phyllosilicate (Liu et al., 2018).In addition, minor content of toxic F (1.0 wt%) and P 2 O 5 (0.9 wt%) are presented, which are consistent with the previous …

Filler-grade calcium silicate from this source can be regarded as a synthetic, precipitated mineral product due to the fact that the fly ash is subjected to strong alkali, which dissolves the silica content. Addition of CaO particles then yields calcium silicate. Song et al. (2012) and Zhang et al. (2013) evaluated its use as a filler for paper ...

Glass cullet from the crushing of post-consumer glass is readily available in urban areas. It can be added in small quantities (probably < 20%) into many mixes, but its smooth surface means that it is difficult to achieve a good bond with the surface. Glass dust is a hazardous irritant, so appropriate health and safety precautions must be taken (see Section 7.4.3).
