Quenching of red-hot clinker is a unique process of producing white clinker. It is necessary to cool the clinker temperature out of kiln from 1200 °C to below 600 °C in a few seconds by quenching with air or cold water, to that would occur in the presence of oxygen, affecting negatively the whiteness of the clinker.
By adding water to a clinker (in the absence of gypsum) partially or totally hardening occurs due to the start of the hydration reactions of clinker …

2.2.3.2.2 Impact of Slag on Clinker Hydration. ... The filler effect promotes clinker hydration by increasing the effective water/cement ratio and providing nucleation sites[3]. Berodier and Scrivener [93] further stated that the provision of nucleation sites alone was insufficient to explain the effect. They further recognized the importance ...
re Impact of P2O5 in clinker and cement chemically? A higher P2O5: 1.Accelerates the clinkerization reaction. 2. Reduces the intensity of internal volatile cycle. 3.Reduces the early strength. 4.Reduces C3S content. Limiting Range should be : 0-1%. Preferable range should be : 0.3- 0.5%. Reply

According to the data statistics obtained in the actual production, the coal ash infiltration in the process of calcination will cause the lime saturation factor in the clinker to be reduced by 0.04 ~ 0.16, the silicon ratio to be reduced by 0.05 ~ 0.20, and the aluminum ratio to be increased by 0.05 ~ 0.30.

The cooling was mad suddenly for clinker by three water types at the same time. The paper discusses the physical and chemical analysis and algal detection of all water types.
clinker. The bigger the water-cement ratio, the longer the setting time; The larger amount of clinker, the faster the hydration rate, and the shorter the setting time. So, setting time were infl uenced by both the two roles, which tended to become short but both of the two clinker reached maximum with 4% addition and then

Cement hydration. Clinker is anhydrous without water having come from a hot kiln Cement powder is also anhydrous if we ignore the small amount of water in any gypsum added at the clinker grinding stage The reaction with water is termed hydration This involves many different reactions, often occurring at the same time...
Clinker can be substituted with other cement-like materials, including waste from coal combustion and steelmaking. This can affect the cement's properties, however, so is only suitable for some end uses. The world average clinker ratio (clinker:cement) fell to 0.65 in 2014, with a large range from 0.57 in China to 0.87 in Eurasia.

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.
The reduction of water and cement clinker leads to a relative GWP of approximately 3 kg CO 2-eq/(N/mm²) notwithstanding the compressive strength. It can be further noticed that the reduction of environmental impact in comparison to conventional concrete was more remarkable for low- and medium-strength concrete.
