The term calcium-silicate composite can be recalled several basic building materials. most common representatives are lime-silicate bricks and autoclaved aerated concrete. It is any material based on the reaction of lime siliceous raw material. In this paper, attention paid to composites concrete production technology. Possibilities lightening utilizing waste expanded perlite as a secondary wer...

We report on the deposition and characterization of hafnium silicate aluminium thin films for different applications in optics electronics. Pulsed laser a controllable oxygen atmosphere was used as processing technique, with optimized parameters terms wavelength, fluence pressure. The were investigated using atomic force microscopy, spectroscopic ellipsometry, UV–VIS spectroscopy X-ray photoele...

The present study firstly proposed a method of integrated utilization of sewage sludge (SS) and coal gangue (CG), two waste products, for cement clinker products with the aim of heat recovery and environment protection. The results demonstrated that the incremental amounts of SS and CG addition was favorable for the formation of tricalcium silicate (C₃S) during the calcinations, but excess amou...

Unique quantitative bioaccessibility data has been generated, and the influence of surface/material and test media characteristics on the elemental release process were assessed for silicon containing materials in specific synthetic body fluids at certain time periods at a fixed loading. The metal release test protocol, elaborated by the KTH team, has previously been used for classification, ra...

Abstract Dicalcium silicate, which is found in steelmaking slag for dephosphorization, exists as the hexagonal α phase at high temperatures. The ‐dicalcium silicate forms a solid solution with tricalcium phosphate entire composition range, although reason solubility of phosphorus remains unclear view crystal structure. It has previously been reported that structure consists symmetric arrangemen...

Dissolving lithium chloride and aluminium chloride in boiling para- or meta-xylene and keeping the colourless solution at room temperature led to crystal growth of a new modification of lithium tetra-chlorido-aluminate, LiAlCl4, which represents a second modification (oP12, Pmn21) of the ternary salt besides the long known monoclinic form [LiAlCl4(mP24, P21/c); Mairesse et al. (1977 ▸). Cryst. ...
