Abstract:
This work concerns the hydration mechanism of calcium zirconium aluminate as a ternary compound appearing in the CaO-Al2O3-ZrO2 diagram besides the calcium aluminates commonly used as the main constitutes of calcium aluminate cements (CACs). Moreover, a state-of-the-art approach towards significant changes in hydraulic properties was implemented for the first time in this work, where the effect of structural modification on the hydration behavior of calcium zirconium aluminate was proved by XRD, 27Al MAS NMR and SEM-EDS. The substitution of Sr2+ for Ca2+ in the Ca7ZrAl6O18 lattice decreases th

Abstract:
This paper discusses studies regarding the impact of fine-ground glass additives on the hydration and properties of alumina cement pastes and mortars. Fine-ground glass was added to pastes and mortars instead of high-alumina cement and calcium aluminate cement in quantities of 5% and 10%. The findings are inconclusive as to the impact of glass on the properties of tested alumina cement types. The effect produced via the addition of glass instead of cement depends on the type of alumina cement used. Adding fine-ground glass to high-alumina cement enhances the paste’s density while improving pas

The contact strength of the C-S-H phase with additions of portlandite, silica and alumina zols, high-aluminate slag was estimated by hyper-pressing method with subsequent destruction. It was established that the contact strength of the cement phase increases in proportion to the specific pressing pressure, the age of samples and inversely the phase basicity reaching 12 MPa.

Abstract:
In calcium aluminate cement (CAC) systems the hydration process is different than portland cement (PC) systems. The hydration products of CAC are subjected to conversion depending on temperature, moisture, water-cement ratio, cement content, etc. Consequently, strength of CAC system can be seriously reduced. However, presence of other inorganic binders or additives may alter the hydration process and improve various properties of CAC based composites. The objective of this study is to investigate the temperature effect on the behaviour of CAC based composite binders. Throughout this research,

In 1995, the Swedish government recommended the discontinuation of amalgam as restorative in paediatric dentistry. Because the mercury content in amalgam constitutes an environmental hazard, its use has declined. The use of resin composites is increasing, but the polymerisation shrinkage of the material is still undesirably high, and the handling of uncured resin can cause contact dermatitis. A new restorative material has recently been developed in Sweden as an alternative to amalgam and resin composite: a calcium aluminate cement (CAC).

Reactive metals such as aluminium metal make up a significant proportion of the UK’s legacy radioactive waste. Current treatment methods – encapsulation in PC-based cementitious systems – do not perform optimally when applied to reactive metals. Corrosion of encapsulated aluminium, caused by the availability of free-water and highly alkaline pore solution, results in expansive corrosion products and the generation of significant quantities of hydrogen gas, which compromises the long-term performance of waste packages.

Abstract:
Calcium aluminate cement (CAC) is used as a protective lining to combat attack by microorganisms and their metabolic products on reinforced concrete sewer pipes. CAC corrosion behaviour is related to the conversion process of the aluminate hydrates. Full conversion can result to a 5-8 times increase in corrosion rate. Hence, understanding and controlling the rate and the processes that affect conversion is important in the effective use of CAC as a mitigation strategy against the attack of microorganisms.

Abstract:
Additions of 0.1 - 1.0 wt% Na on Al2O3-CaO and Al2O3-CaO-SiO2 model refractory castable systems were investigated with respect to the effect on formation characteristics, and mechanical properties of the consolidated refractory. In the Al2O3-CaO system, sodium is shown to form sodium β-alumina (NaβA) via the intermediate NaAlO2. Formation of NaβA disrupts the reaction path of calcia (CaO) with alumina (Al2O3), delaying crystallisation of calcium hexaluminate (CA6) from 1350 to 1500 °C. The linear expansion associated with NaβA is quantified and is shown to scale with the amount of dopant added

However, the high temperature conditions to be found in such wells, up to 400–500 °C, are very challenging and may be detrimental for the integrity of well cement.
