Tricalcium Silicate - an overview ScienceDirect Topics

The hydration products for C 3 S and C 2 S are calcium silicate hydrate (C 3 S 2 H) and calcium hydroxide (Ca(OH) 2), also known as Portlandite. The C 3 S 2 H 3, calcium silicate hydrate, has variable C:S and H:S ratio depending on the temperature, calcium concentration in the aqueous phase, additives, and aging. The material is quasiamorphous ...

Isotopic Evidence for Variations in the Marine Calcium ...

2000-8-18  The δ 44 Ca of the modern weathering fluxes can be estimated from measurements of rocks, river waters, and marine carbonates. Silicate rocks have a δ 44 Ca of +0.3 to −0.3‰ with an average close to 0‰ ().The δ 44 Ca values for six large rivers (normalized to the standard we are using) are slightly lower than this, yielding an average δ 44 Ca of −0.3 ± 0.2‰.
