clinker c3s paramount - international cement review

2013-3-18 · Increasing C3S content Achieving a high C3S content of clinker might be thought to be relatively simple. Clinker C3S contents of up to ±67 per cent in grey cement clinker can be achieved by raising the lime saturation of the clinker towards 100 per cent

cement clinker quality control during clinker production

Under the low-temperature condition, CaO in the raw meal is not fully absorbed to form C 3 S but exists in free state, which makes the strength of calcined clinker decrease. If the temperature in the kiln is too high, the size of the clinker will increase, which makes the clinker dense and hard to grind

cement clinker - an overview | sciencedirect topics

A series of chemical reactions of calcium, silicon, alumina and iron oxides present leads to the formation of the clinker material with main compounds tricalcium silicate (C 3 S), dicalcium silicate (C 2 S), tricalcium aluminate (C 3 A) and tetracalcium aluminoferrite (C 4 AF). After cooling and storage, the clinker is ground into a fine cement powder and gypsum is added, as a source of calcium sulphate, to improve the future setting behaviour of the cement

2020-3-21 · The main clinker phase of ordinary Portland cement accountable for structure development is tricalcium silicate which main hydration product is calcium silicate hydrate (C–S–H, C—CaO, S—SiO 2, H—H 2 O, according to construction chemistry nomenclature). Mature cement stone consists of approximately 80 wt% C–S–H phases which make

the influence of c 3 a content in cement on the chloride

2016-11-7 · The influence of C 3 A on setting and hardening of fresh concrete is very crucial. As seen in Figure 2, the penetration resistance of fresh mortar obtained immediately after casting was strongly dependent on the C 3 A content in cement clinker; an increase in the C 3 A in cement resulted in a rapid hardening. For example, the fresh mortar specimen containing 16.9% of C 3 A was hardened at 78
