Water radiolysis is a major concern for the conditioning of radioactive waste in cement materials. Synthetic calcium silicate hydrates (C-S-H), main concrete, were synthesized with different to ratios and relative humidity. The samples irradiated under γ- electron beam irradiation. radiolytic hydrogen production was quantified radiation induced defect produced at low temperature characterized b...

This paper presents the development of composite silicate mass compositions based on man-made waste for production autoclave hardening products, as well results physico-chemical studies hydration products materials. The possibility, expediency and efficiency using multi-tonnage technogenic Kazakhstan in industry building materials is shown. Based conducted research, composition a burnt carbonat...

AIM To report the hydration mechanism of white mineral trioxide aggregate (White MTA, Dentsply, Tulsa Dental Products, Tulsa, OK, USA). METHODOLOGY The chemical constitution of white MTA was studied by viewing the powder in polished sections under the scanning electron microscope (SEM). The hydration of both white MTA and white Portland cement (PC) was studied by characterizing cement hydrate...

• Ferrite-Rich Portland cement produces denser microstructure at an early age compared with ordinary cement. Fe-siliceous hydrogarnet is the main Fe-containing phase in hydrated Fe(III) ions exist as Fe(OH) 4 ? high-pH pore solution. C-S-H adsorbs via surface complexation reaction and around 2 wt% of Fe incorporated [C-(F)-S-H] produced The hydration process ferrite-rich (FC) its structure have...
