The aim of this study is to investigate the durability of geopolymer mortars based on waste-glass powder (WGP) and calcium aluminate cement (CAC) exposed to acid attack. Geopolymer specimens were prepared by a combination of WGP and CAC activated by an aqueous solution of sodium hydroxide and sodium silicate and were cured under hydrothermal conditions.

From this experiments, the calcium–aluminate-based LFS powder, though it is slowly cooled, shows a high content of reactive mineral of C 12 A 7 and low vitrification of 19% in the material stage. Also, if it does not make contact with water during cooling, its mortar mixture shows a very short setting time of 8 min and high compressive

It is widely used in mortar concrete. Calcium aluminate cement is also named as "aluminous cement", "high-alumina cement" and "CAC cement" . It is application for chemical constructions and refractory industry. The hydration products in CSC/CAC composite are gehlenite (Ca 2 Al 2 SiO 7 ·8H 2 O), calcium aluminate hydrate (Ca 3 Al 2 O 6 × H 2 O), and katoite (Ca 2 Al 2 O 6 ·6H 2 O). Platelike crystals were found in the microstructure.

Pure β-dicalcium silicate and monocalcium aluminate powder were prepared by Pechini method.A series of calcium silicate/calcium aluminate cements

The reactive aluminates react with water initially to form a mixture of: Calcium Aluminate is generally immediately available in most volumes. Aluminates are compounds with a negatively-charged alumina ion and a metallic oxide with various industrial applications such as water treatment and ceramics manufacturing. Seven batches of calcium aluminate powder containing different ratios of alumina and calcium oxide were chemically prepared by thermal decomposition method. The produced powder was investigated in terms of phase composition and morphology by XRD pattern and scanning electron microscope (SEM). Preparation of calcium aluminate pastes.

It is essentially Fondu clinker, crushed and sized into grades commonly needed by concrete and castable formulators. Calcium aluminate cement is cement formed from the combination of limestone and alumina at high temperatures.
