The possibility of obtaining building foamed glass-ceramic using the diamond concentration tailings Lomonosov deposit in Arkhangelsk Region, Russia, is demonstrated here. effect tailings’ particle size distribution, feed temperature, addition a foaming agent, and content oxidizer on charge established. process conditions for materials are described. specifications with optimal composition (tail...

Most cellular solids are random materials, while practically all theoretical structure-property relations are tor periodic models. To generate theoretical results for random models the finite element method ( FEM) was used to study the elastic properties of open-cell solids. We have computed the density ( I J ) and microstructure dependence of the Young's modulus ( E ) and Poisson's ratio ( v )...

This paper presents an investigation of ultimate load, maximum deflection and failure mode foamed concrete composite slabs (FCCS). Of interest are the effects dry density slab thickness. Unlike conventional slabs, FCCS has advantage eliminating selfweight penalty thus reducing underlying structural members.With advanced research in technology, with sufficient strength propertiesto meet requirem...

polyaniline and polyamide (nylon 6,6) nanocomposites with silva were prepared by in-situ oxidativepolymerization of aniline monomers in the presence of ag salt nano particles of silver (nps) were symthesieedby controlled reduction of ag+ ions kith sodium borohydride at room temperature. nylon 6,6 wax loaded withag nanoparfieles by erdrapment of ag+ ions into the polymer network, followed by red...

in order to determine the prevalence, incidence and odd ratio of hbv, 681 serum samples were collected from 54 laboratory personnel in tehran in both private and governmental sectors. the samples were tested for hbsag and ab using elisa technique. the results showed that the prevalence of hbsag and ab among clinical laboratory personnel was 2.3 and 20 percent respectively. the prevalence of hbs...

Latent Heat Thermal Storage (LHTS) based on Phase Change materials (PCMs) offers a promising solution for efficient utilization of intermittent energy from renewable sources. The primary limitation is the poor thermal conductivity PCMs, which requires employing performance enhancement techniques. To enhance PCM storage, copper foam with high porosity embedded PCM. A numerical simulation model h...
