WebThe extent of the clinker reactions in NFM slag and LS blended pastes was determined by QXRD. The bound water generated for each g of reacted clinker (i.e. the total of all clinker phases) was estimated at 0.35 g BW/g reacted clinker from the bound water and reaction extent of the clinker phases in the PC reference paste without slag or limestone.

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 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone … See more The Portland clinker essentially consists of four minerals: two calcium silicates, alite (Ca3Si) and belite (Ca2Si), along with tricalcium aluminate (Ca3Al) and calcium aluminoferrite (Ca4AlFe) (Ca3Si), Ca2Si, Ca3Al, Ca4AlFe … See more Portland cement clinker (abbreviated k in the European norms) is ground to a fine powder and used as the binder in many cement products.

WebIn Portland cement clinker, tricalcium aluminate occurs as an "interstitial phase", crystallizing from the melt. Its presence in clinker is solely due to the need to obtain liquid at the peak kiln processing temperature (1400–1450 °C), facilitating the formation of the desired silicate phases. WebMar 29, 2024 · In order to realize low energy consumption in cement and the recycling of solid waste, the phase composition and structure of waste mortar used to prepare a high belite cement clinker, instead of some other raw materials, have here been investigated, and the belite was activated by doping with SO3.

WebThe spatial arrangement of the clinker phases within unground clinker particles typically shows a dependence on Ca content. Amorphous silica is enclosed by wollastonite, as the calcium silicate with the lowest Ca content. On the other hand, belite as the calcium silicate with the highest Ca content is spatially linked either to rankinite or ... WebJun 1, 2024 · The materials are composed of both reactants and products at mesoscale. On the reactant side, the volume occupied by the four clinker phases is linearly related to the clinker hydration degree, i.e., (23) V X (t) = V X 0 (1 − ξ X (t)), where V X 0 are the initial volumes of the clinker phases X in the cement, and (24) V X 0 = V c 0 × m X ...

WebAFt phases are important hydration products of the cement clinker. They are crystalline hydrates with generic formula 3CaO· (Al,Fe)2O3·3CaX·nH2O when also taking into account the possible substitution of the aluminium ion ( Al3+) by the ferric ion ( Fe3+ ). They are formed when tricalcium aluminate ( 3CaO·Al2O3, also noted C3A) reacts with ...
