·The valorisation of waste or by products in Portland clinker production is a promising alternative for developing sustainable cements The complexity of the chemical reactions during clinkering
·Fine powder was produced by grinding the dried particles with an agate mortar The particle size of samples was < 45 μm for the X ray powder diffraction XRPD test and < 74 μm for the TGA DTA test Influence of alkali sulfates in clinker on the hydration and hardening of Portland cement Constr Build Mater 180 2018 pp 351 363
·Alite constitutes 50 70% of OPC and upon hydration is responsible for the strength development up to 28 days and is generally easier to grind The main clinker phases in CSACs are ye elimite Ca 4 AlO 2 6 SO 4 belite and calcium sulfate CaSO 4

·Ultra fine tailing cementitious activity index increased from to by grinding • Mine backfilling requirements were met with a slurry concentration of 78% • The hydration products formed in the G3 sample greatly improved its strength • C − S − H and C− A S − H gel augmentation increased less harmful pores from to
·clinker grinding processes From calorimetric measurements of the heat of cement hydration the polyols tested were also shown to exert a moderate acceleration of the hydration reactions Hence selected polyol type compounds can be useful in cement grinding aid formulations which simultaneously aim to improve grinding efficiency and control cement
·Calcined attapulgite CAG is a fibrous calcined clay with strong pozzolanic activity which is a good candidate for the development of cementitious materials to meet the requirements of CO2 emission reduction In this paper the effects of CAG on the early hydration microstructure and mechanical properties of cementitious materials were evaluated and the
·The inclusion of high specific surface materials such as calcined clays in cementitious systems enhances the hydration of clinker products at very early ages but it may also increase water demand; thus the pursuit of a flowing concrete may demand an increase in the dosage of superplasticizers The grinding regime can have a major influence on the
·Its hydration is complex but can be represented very roughly by the equation 2 Ca 3 SiO 5 6 H 2 O → Ca 3 Si 2 O 4 OH On grinding clinker alite is brittle and breaks easily Belite on the other hand is tougher although not necessarily much harder and tends only to deform on impact The aluminate and ferrite are also somewhat
·In this case no significant effect of the grinding aids on the hydration kinetics of LC 3 systems is observed The total heat release is in all cases similar to the system without the addition of grinding aids The three alkanolamines have different effects on clinker hydration and the precipitation of hydrates as seen in Fig 7 and Fig

The maximum feed particle size of the vSMM used was limited to about 2 mm so that the clinker was pre ground beforehand to a specific surface area of about 3700 cm 2 /g Blaine and a RRSB position parameter x of 13 μm When the grinding plant was operating in a stable condition with pure clinker the grinding temperature was about 75 °C

·The hydration of LC 3 is influenced by the content of metakaolin in the calcined clay [13] gypsum [18 19] and Ca OH 2 from the hydration of alite and belite in the clinker [20] Consequently
Grinding The cooled clinker is then ground into a fine powder with the addition of a small amount of gypsum This process enhances the reactivity of the clinker and allows it to harden when mixed with water thus forming cement This clinker has properties that reduce the heat generated during the cement hydration process It is beneficial
Use of cement grinding aids to optimise clinker factor This is due to the fact that most of the published data deal with the hydration processes and interaction mechanisms of the main cement compounds in the presence of GAs For example Ramachandran 1976 studied the hydration and hardening characteristics of C3 A with or without gypsum
