Cement Chemistry

TiO2 is present in all clinker phases, expecially ferrite (C4AF) in which it has a maximum solubility of 18% (compared to only about 1 or 2 % in the other clinker phases). Therefore it certainly contributes to the liquid phase, but I am not aware of any liquid phase formula that takes TiO2 into account.

Calculation of the C 3 A Percentage in High Sulfur Clinker

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...

The iron content of the clinker therefore fixes the ferrite content. Secondly, the aluminate content is fixed by the total alumina content of the clinker, minus the alumina in the ferrite phase. This can now be calculated, since the amount of ferrite phase has been calculated.

The enthalpy change at 25°C is +43.989 kJ/mol: at 100°C it is +40.865 kJ/mol. The typical clinker mentioned above has 1.5429 kg of notional dry rawmix per kg clinker made, and if this takes the form of a slurry with 38% free moisture, then 0.9456 kg (52.49 mol) of water must be evaporated, with a heat input of 2145 kJ/kg clinker.

CALPHAD formalism for Portland clinker: thermodynamic ...

Liquid phase gets supersaturated with respect to CH. As a result CH starts precipitating and this stops the further dissolution of C 3 S. The end of the dormant period can come about in many ways: The barrier can weaken due to ageing. Diffusion of ions can occur across the barrier by osmosis.

Calculation of the C3A Percentage in High Sulfur Clinker ...

Aug 15, 2020· As long as the stationary phase is more polar than the mobile phase, it is considered normal phase chromatography. The stationary phase is usually a column packed with silica particles that have R groups attached. Common R groups for normal phase are -C 2 H 4 CN or -C 3 H 6 NH 2.

This determines the potential relative proportions of aluminate and ferrite phase in the clinker. An increase in clinker AR means there will be proportionally more aluminate and less ferrite in the clinker, in addition to characterizes the composition of the melt and its viscosity in the clinker; low AR <1.5 increases the Fe 2 O 3 content, decrease the viscosity and increase infiltration of ...

content of carbide slag and its raw material was not favorable to reduce the minimum eutectic temperature, the quantity of liquid phase may be less, and the liquid viscosity was increased leading to poor burn-ability, which was not helpful for sintering of clinker and formation of C 3S.

The liquid–liquid interface moves up in the vessel toward the top of the liquid column until, at overall composition (zB=0.92) (point c), there is only one liquid phase. Now suppose the system point is back at point a and we raise the temperature while keeping the overall composition constant at (zB=0.40).

present in the clinker. The amount of melt phase in the burning zone is a function of the silica moduli. Increasing silica moduli impairs the burnability of the clinker by reducing liquid phase content and tendency toward formation of coating in the kiln. Also, increasing silica moduli causes a slow setting and hardening of the cement.

Apr 20, 2019· At the lowest eutectic temperature, the mixed raw material forms liquid phase. C 2 S and f-CaO gradually dissolve, diffuse and form C 3 S minerals in the liquid phase (Rodrigues et al., 2017). The reaction formula is: C 2 S + CaO → liquid phase C 3 S. Therefore, f-CaO is used to indicate the unformed C 3 S. G can be calculated using equation .
