The paper presents a study of structure formation during the hardening new water resistant hydraulic magnesium cement. Improvement resistance and manifestation properties in cement are associated with use fundamentally mixing liquid involving bicarbonate solution. Use this solution makes possible for composition to harden not only air, but also water. Coefficient is 1.0–1.8. When an aqueous bicarbonate, main products hydroxide hydrocarbonates. increase hydrocarbon phase contributes...
The core catcher is arranged in an unattended, unventilated sub-reactor space. It designed to receive molten corium emergencies, and thus the concrete used must be resistant high temperatures without significant loss of strength. During nuclear power plant (NPP) operation, these concretes are subjected considerable radiation exposure, which may also affect their physical–chemical properties. Concrete mixes based on Portland cement alumina with iron corundum aggregate were investigated. Model...
Abstract Anion exchange resins are widely used in template synthesis of oxide composites. The present work is aimed to study the thermal destruction anion exchangers with divinyl‐benzene and polyacrylate matrices order obtain hollow spherical MoO 3 /TiO 2 –SiO composites from these preliminarily saturated paramolybate ion coated tetrabutoxytitanium sol tetroethoxysilane. It shown that processes decomposition affect strength Decomposition resin a matrix, accompanied by random nucleation...
The aim of this work was to synthesize nanostructured MoO 3 /TiO 2 -SiO composites with hollow spherical shape by thermal decomposition anion exchangers saturated Mo 7 O 6- 24 ions and treated the TBT-TEOS sol.The effect kinetics (Kissinger Metzger-Horowitz methods) resins porous gel structures on size nanoparticles strength spheres shown.The formation dense agglomerates composite is facilitated reactions occurring at interface between phases cylindrical symmetry when using an exchange resin...

Abstract Temperature characteristics, stages and thermal effects of the processes occurring during thermolysis TOKEM-320Y anion-exchange resin in an atmosphere air were determined by differential analysis. The activation energies orders reactions decomposition calculated Kissinger Metzger-Horowitz methods using TG curves obtained at different heating rates resin. Models are proposed that most accurately describe temperature range 25–800 °C.
