Compounds in Cement and Their Influence on Concrete

The chemical formula of tricalcium aluminate (C 3 A) and tetracalcium alumino ferrite (C 4 AF) are 3CaO.Al 2 O 3 and 4CaO.Al 2 O 3 Fe 2 O 3, respectively. The compound tricalcium aluminate (C 3 A) is characteristically fast reacting with water and may lead to an immediate stiffening of paste and this process is termed flash set.

17.09.2013· Functions of Tricalcium Aluminate. Contributes to strength development in the first few days because it is the first compound to hydrate . It turns out higher heat of hydration and contributes to faster gain in strength. But it results in poor sulfate resitance and increases the volumetric shrinkage upon drying. Cements with low Tricalcium Aluminate contents usually generate less heat, develop

Tricalcium Aluminate - roughly Ca 3 Al 2 O 6; Tetracalcium Aluminoferrite - roughly Ca 2 (Al,Fe) 2 O 5; All these chemical formulae are "rough" because the phases are actually solid solutions, and the atoms of the formula are substituted to a small but significant extent by other elements. For instance, some of the calcium loions in the belite crystal can be occupied by magnesium, and some of the …

Modifying the Bogue calculation

31.01.2018· The calculation is based on the assumption that the phases are present as pure tricalcium silie, dicalcium silie, tricalcium aluminate and tetra-calcium alumino-ferrite and that the reactions in the kiln are allowed to progress to equilibrium. In practice neither of these assumptions is true. The value of the Bogue calculation remains a way of assessing the potential compound composition
