TL;DR: In this article, the filling role of pozzolanic material was analyzed and the influence of this material on fluidity and strength of cement was also investigated, showing that the fine material can increase the packing density and reduce the amount of water in surface layer and decrease the filling water.

TL;DR: In this article, the combined effects of waste polyethylene terephthalate (PET) particles and pozzolanic materials on the rheological, mechanical and durability properties of self-compacting concrete (SCC) are evaluated.

TL;DR: In this article, the influence of silica fume (SF) addition on electromagnetic interference shielding effectiveness (EMI SE) of cement matrix materials that incorporated both SF and multi-walled carbon nanotubes (MWNT) with varying weights was investigated.

TL;DR: In this paper, it was shown that amorphous silica can be reduced to polycrystalline silicon by magnesium at a comparatively low temperature (about 600°C) using differential thermal analysis and thermogravimetric analysis.

TL;DR: In this article, nanoindentation was used to investigate the microstructures of cementitious composites containing silica fume and fly ash, and the mechanical properties (elastic modulus and hardness) of individual phases (like outer product, inner product, calcium hydroxide, fly ash particles, residual cement grains) were investigated and analyzed.
Abstract: In this study, nanoindentation was used to investigate the microstructures of cementitious composites containing silica fume and fly ash. With the help of scanning electron microscope, the mechanical properties (elastic modulus and hardness) of individual phases (like outer product, inner product, calcium hydroxide, remained fly ash particles, residual cement grains) in cementitious composites containing silica fume and fly ash were investigated and analyzed. Additionally, this study examined the differences between the ‘C–S–H’ phases in the different cementitious composites and provided an insight into the influence of mineral admixtures (silica fume and fly ash) on the properties of the ‘C–S–H’ phase.
