Cement chemist notation (CCN) was developed to simplify the formulas cement chemists use on a daily basis. It is a shorthand way of writing the chemical formula of oxides of calcium , silicon , and various metals .
Alite is an impure form of tricalcium silicate, Ca 3 SiO 5, sometimes formulated as 3CaO·SiO 2 (C 3 S in cement chemist notation), typically with 3-4% of substituent oxides. [1] It is the major, and characteristic, phase in Portland cement.
Belite is the mineral in Portland cement responsible for development of "late" strength. The other silicate, alite contributes "early" strength, due to its higher reactivity. Belite reacts with water (roughly) to form calcium silicate hydrates (C-S-H) and portlandite (Ca(OH) 2 ) according to the reaction:
Calcium silicate hydrate (also shown as C-S-H) is a result of the reaction between the silicate phases of Portland cement and water. This reaction typically is expressed as: 2 Ca 3 SiO 5 + 7 H 2 O → 3 CaO · 2 SiO 2 · 4 H 2 O + 3 Ca(OH) 2 + 173.6 kJ. also written in cement chemist notation, (CCN) as: 2 C 3 S + 7 H → C 3 S 2 H 4 + 3 CH + heat
Cement clinker is a solid material produced in the manufacture of portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 ...
Hatrurite, a phase in cement clinker (alite, C3S), was first described in 1977, for instance. [14] Some mineral names were revised; this changed their first letters. Sodium-pharmacosiderite is now natropharmacosiderite, natroapophyllite is now fluorapophyllite-(Na), for instance.
C3S may refer to: Alite, in cement chemist notation; Chennai Centre for China Studies, an Indian think thank; Copernicus Climate Change Service, science service; Cultural Commons Collecting Society, music licensing organization; Tricarbon monosulfide (C 3 S), substance
