Microstructure development in mixes of calcium aluminate cement with silica fume or fly ash

, 2009
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.

The kinetics of ettringite formation and dilatation in a blended cement with beta-hemihydrate and anhydrite as calcium sulfate

, 2005
The phase formation, heat of hydration and dilatation in a blended cement consisting of 50 wt.% calcium aluminate cement, 25 wt.% Portland cement and 25 wt.% calcium sulfate were studied (w/c= 1).

The Hydration and Calcination Mechanism of Calcium Aluminate-Based Ultra-High Strength Cement with Calcium Sulphoaluminate Compound

, 1989
The hardening shrinkage of calcium aluminate based ultra-high strength cement becomes nearly zero by using calcium sulphoaluminate compound, and very high bending strength can be obtained by calcinating at 300°-600°C.

Hydration study of a calcium aluminate cement blended with anhydrite

, 2014
The influence of calcium aluminate cement (CAC) to calcium sulfate (CS-) ratio on the hydration at water to binder ratio (w/b) 0.4 and 0.7 has been investigated.

Influence of Calcium Aluminate Cement Addition on the Hydration and Strength of Limestone Calcined Clay Cement

Limestone calcined clay cement (LC3) is an alternative cement that allows reduction by up to 40% of the CO2 emissions per ton of cement produced. With this green binder, it is possible to replace 50% or more of Portland cement (PC) while maintaining ...
