Expert Reviews

Dr. Ms. Guixin (Susan) Ph.D (Switzerland-Institute for Inorganic Chemistry, Zurich, Switzerland)

Tricalcium aluminate Ca3Al2O6, often formulated as 3CaO·Al2O3 to highlight the proportions of the oxides from which it is made, is the most basic of the calcium aluminates. It does not occur in nature, but is an important mineral phase in Portland cement.

Dr. Ralph Bressler PhD (Belarusian State Technological University, Minsk, Belarus)

Pure tricalcium aluminate is formed when the appropriate proportions of finely divided calcium oxide and aluminium oxide are heated together above 1300 °C. The pure form is cubic, with unit cell dimension 1.5263 nm and has density 3064 kg·m−3. It melts with decomposition at 1542 °C.

Dr. Huojin Chan (University of Science and Technology of China, Hefei, Anhui, China)

The structure of pure liquid tricalcium aluminate contains mostly AlO4 tetrahedra in an infinite network, with a slightly higher concentration of bridging oxygens than expected from the composition and around 10% unconnected AlO4 monomers and Al2O7 dimers 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 phase.

Dr. Hans Roelofs Ph.D (National Technical University of Athens, Greece)

Tricalcium aluminate is associated with three important effects that can reduce the durability of concrete: heat release, which can cause spontaneous overheating in large masses of concrete. Where necessary, tricalcium aluminate levels are reduced to control this effect
