Stabilization of Cr(III) wastes by C3S and C3S hydrated matrix : comparison of two incorporation methods [PDF]
, 2015 In the present study, the influence of Cr(III) on the properties of C3S and its stabilization in C3S hydrates was investigated by either direct incorporation as Cr2O3 during C3S preparation or introduced as nitrate salt during hydration.

Structural models of random packing of spheres extended to bricks: Simulation of the nanoporous calcium silicate hydrates [PDF]
, 2009 Structure simulation algorithms of random packing of spheres and bricks have been developed. These algorithms were used to reproduce the nanostructure of the cementitious calcium silicate hydrates. The textural parameters (specific surface area, porosity,

The use of Bioceramics as root-end filling materials in periradicular surgery: a literature review [PDF]
, 2018 Introduction: Periradicular surgery involves the placement of a root-end filling following root-end resection, to provide an apical seal to the root canal system. Historically several materials have been used in order to achieve this seal.

Physicochemical and Biological Properties of Mg-Doped Calcium Silicate Endodontic Cement
Materials, 2021 Calcium silicate-based cement has been widely used for endodontic repair. However, it has a long setting time and needs to shorten setting time. This study investigated the effects of magnesium (Mg) ion on the setting reaction, mechanical properties, and

Comparative Study of Soil Grouting with Cement Slurry and Cement-Sodium Silicate Slurry
Advances in Materials Science and Engineering, 2018 Cement slurry and cement-sodium silicate slurry are most widely applied for soil grouting reinforcement project. The viscosity change of cement slurry is negligible during grouting period and presumed to be time independent, while the viscosity of cement-
