Sep 12 2014 In this study calcium silicate hydrateCSH with CaOSiO2 ratio of 1.5 target mixture is synthesized and C1.27SH0.76 with 93.4 purity is obtained. The dried CSH was compacted at 8 MPa to 20 mm 20 mm 20 mm for accelerated carbonation. The carbonation products and carbonation degree of synthetic calcium silicate hydrate are characterized and quantitatively evaluated by QXRD.

Jan 01 2014 Precipitated calcium carbonate a widely used filler material is nowadays mainly produced by the so-called carbonation process. Natural limestone is first calcined and then contacted with carbon dioxide to precipitate particles of a controlled purity size and morphology.
Calcium carbonate Calcium carbonate or limestone is an odorless white grayish-white or yellowish-brown substance that is processed in the size of a piece of rock to micronized powder. Limestone refers to any rock that is mostly composed of calcium carbonate and has the chemical composition CaCO3 of which 65 is CaO and 44 is CO2.
