The article presents a study which investigates on the effect of adding alumina on the physical and mechanical properties of β-tricalcium phosphate (TCP) conducted to samples that were prepared by uniaxial pressing.

The article examines the influence of cement type on the performance of special concretes which are designed by computing techniques. It notes that the fresh properties of the cement were assessed by measuring the fluidity index and the mechanical strength was evaluated using the compressive and three-point bending tests. It concludes that by comparing the properties, the concretes produced with Portland cement displayed better performance and efficiency as compared to calcium aluminate cement.

The article discusses a study which examines the impact of the binder, which is the calcium aluminate cement, on alumina-magnesia castables. It cites the expansive behavior of alumina-magnesia castables when treated at high temperatures and the changes in the properties of such materials including volumetric stability if the binders are changed. Moreover, the study reveals that the binder systems can be employed in designing the expansion of these castables.

The article focuses on the study on how the contents of hydraulic binders affect the magnesium oxide hydration in refractory castables. It notes that magnesia sinter hydration behavior in aqueous suspensions can be modified with the presence of calcium aluminate cement and hydratable aluminum oxide. It mentions that the binder contents reduce the effects of magnesium oxide hydration.

The article presents a study on the effects of the addition of different calcium aluminate cement (CAC) contents on magnesium oxide (MgO) hydration. The study used qualitative X-ray diffraction, pH measurements and volumetric expansion to investigate the effects in aqueous suspensions. The result shows that proper control of the CAC content for the formulations of MgO hydration can be significantly reduced.

The article investigates the impact of calcium aluminate cement (CAC) on in-situ spinel containing magnesia refractory castables. The study showed that CAC affects the volumetric stability of magnesium oxide-spinel system. It presents and discusses the CAC effects on the sintering and in the mechanical properties after sintering at high temperatures.
