The development of biomaterials capable of driving dental pulp stem cell differentiation into odontoblast-like cells able to secrete reparative dentin is the goal of current conservative dentistry. In the present investigation, a biomembrane (BM) composed of a chitosan/collagen matrix embedded with calcium-aluminate microparticles was tested. The BM was produced by mixing collagen gel with a ch...

In this paper, the thermodynamic properties of PbO-ZnO-FeO-Fe2O3-SiO2-CaO six-component slag system were studied by using molecular-ion coexistence theory, and influence composition changes on activity each structural unit was analyzed. The results show that calculated value model is in good agreement with measured experiment, greatly affected slag, but less temperature. High temperature conduc...

This paper investigates the effect of varying solid alkali activators on fresh and hardened properties microstructural changes one-part geopolymers (OPGs). Single binary were used to activate high calcium fly ash. The either solely sodium metasilicate (Na2SiO3) or a combination aluminate (NaAlO2) (Na2SiO3). OPG activated with anhydrous Na2SiO3 achieved an excellent 28-day compressive strength 8...

To get suitable ladle slag which can avoid slag sticking onto the RH immersion tube during RH refining process of IF steel, the effect of composition on melting point and viscosity of RH refining ladle slag was studied by different additives which is based on CaO. The results of melting point and viscosity testing experiments indicates that, the melting point and viscosity of RH refining ladle ...

This is an experimental study on the development of a low-carbon, eco-friendly cement containing calcium sulfoaluminate expansive agent (CSAe), slag, and silica fume (SF). The to be developed has low water/binder ratio (w/b) 0.5 designed used for structural purposes, with focus its mechanical performance. CSAe, SF were mixed at various mixing ratios. main hydration product slag-based CSAe in ex...
