This paper explores the sustainability aspects of binders used in concrete 3D printing. Firstly, a prospective approach to conduct sustainability-assessment based on life cycle printed structures is presented, which also highlights importance considering functional requirements mixes for The potential material production phase emphasized enhance 3DCP by reducing embodied impacts. literature dif...

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...

BACKGROUND The aim of this study is to evaluate the effect of self-invented compound calcium phosphate cement upon the proliferation and osteogenesis of bone mesenchymal stem cells (BMSCs). METHODS Four groups including traditional calcium phosphate cement, modified calcium phosphate cement, modified calcium phosphate cement plus bone morphogenetic protein (BMP), and control groups were estab...

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...

Abstract Purpose This work deals with the application of a solidification/stabilization process aim to obtain safe and reusable granular materials from polluted soil elucidate mechanisms involved in retention several heavy metals. Materials methods The High Performance Solidification/Stabilization (HPSS®) was applied selected contaminated by using both ordinary Portland cement calcium aluminate...
