Microstructure development in mixes of calcium aluminate

The most widely identified degradation process suffered by calcium aluminate cement (CAC) is the so-called conversion of hexagonal calcium aluminate hydrate to cubic form. This conversion is usually followed by an increase in porosity determined by the different densities of these hydrates and the subsequent loss of strength. Mixes of calcium aluminate cement (CAC) and silica fume (SF) or

This is an indiion of the accelerated production of hydration products (C–S, C–S–H) and a sign of more strength development. According to ASTM C618 [ 36 ], materials with 75% pozzolanic index are relatively sufficient to include as supplementary cementitious material, where typical WG powder shows more than 80% pozzolanic index in 28 days age [ 37 ].

Comparative study of hydration of monocalcium aluminate

2019/11/25· Monocalcium aluminate (CaAl2O4, CA) and quaternary (Q) phase (Ca20Al26Mg3Si3O68) are the two principal hydraulic phases in calcium aluminate cement. Their strength development has been reported. However, little information about the difference of their hydration and hydrates composition is available. For this reason, the hydration process of CA and Q phase was investigated …

Accelerator dosages are higher than those for normal concrete, typically in the range of 6 to 8 % admixture by weight of cement, or even higher. The active dry matter contents of commercial liquid shotcrete accelerators are typically in the range of 40 to 50 % (see Table 13.1).

Microstructural development of calcium aluminate cement

Calcium Aluminate Cements (CAC) are renowned in the field of construction for specific appliions requiring rapid hardening and chemical resistance. These properties result from rapid exothermic reactions occurring immediately after setting. Due to the much lower use of CACs compared to Portland cements based materials, there is a lack of knowledge on the hydration of this cement and
