In this study, we investigate calcium aluminate phases that were prepared by three different solid phase synthesis methods and a sol-gel method (with and without EDTA). The purpose of this study is to compare these three methods in terms of achieving higher purity, optimal phase and complexity in the production of the final product. Comparing the results, we found that the sol-gel method is mo...

Coronary artery calcium (CAC) is an established marker to predict major cardiovascular events (MACE), and has incremental value over traditional risk factors (CVRF). CAC widely available, easily reproducible, used in nearly all coronary computed tomography angiography (CCTA) assessment protocols for disease (CAD). The distribution extent of CAC, its prognostic implications local Malaysian patie...

In the present work the internal sulfate attack on pastes made from pure clinker phases was studied. Two binders were produced: (a) a binder with 2% C3A and 18% C4AF content; (b) a binder with 10% C3A and C4AF content each. Gypsum was used as the sulfate bearing compound, while calcium carbonate added to differentiate the binders produced. The phases formed were identified by XRD analysis. The ...

A deeper insight into SO3/Al2O3 ratio including the contribution of alumina in slag at early age is required to ensure a properly sulfated cement. In this paper, investigate effect gypsum and slag, emphasis was laid on hydration characteristics C3S-gypsum-slag system during age, which synthesized laboratory with varying Al2O3 contents from 3.69 18.19 wt%. The duration dormant period C3S depende...
