Is Cement a Glassy Material? [PDF]
arXiv, 2015 The nature of Calcium--Silicate--Hydrate (C--S--H), the binding phase of cement, remains a controversial question. In particular, contrary to the former crystalline model, it was recently proposed that its nanoscale structure was actually amorphous. To elucidate this issue, we analyzed the structure of a realistic simulation of C--S--H, and compared ...

The application of Nano-silica gel in sealing well micro-annuli and cement channeling [PDF]
arXiv, 2023 The possibility for hydrocarbon fluids to migrate through debonded micro-annuli wells is a major concern in the petroleum industry. With effective permeability of 0.1-1.0 mD, the existence of channels in a cement annulus with apertures of 10-300 micrometer constitutes a major threat. Squeeze cement is typically difficult to repair channels-leakage with

Nanoionomer: Evaluation of microleakage
Journal of Indian Society of Pedodontics and Preventive Dentistry, 2011 Background: Glass ionomer cements are widely used in pediatric practice due to their advantage of fluoride release and chemical bond to tooth structure. Adherence of the restorative material to the cavity walls is one of the most important characteristic

Tensile strength of conventional glass ionomer cement and silver reinforced glass ionomer cement
BioinformationA comparative analysis and assessment of the compressive strength (CS) and diametral tensile strength (DTS) between conventional glass ionomer cement (C-GIC) and a silver-reinforced GIC (S-GIC) variant is of interest. Ten specimens of both C-GIC (GC Fuji II, Japan) and S-GIC (Riva Silver, SDI, Australia) were fabricated for the evaluation of ...
