This investigation aims to study the performance of different hybrid binders as environmentally-friendly cementitious soil stabilizers well Nanosilica a reactive powder. Mechanical properties and microstructural analysis in addition molecular mineralogical specifications were investigated evaluate stabilized samples. For this purpose, series experimental tests including scanning electron micros...
Abstract This paper aims to investigate the feasibility of incorporation nanosilica (NS) in ultra-lightweight foamed concrete (ULFC), with an oven-dry density 350 kg/m 3 , regard its fresh and hardened characteristics. The performance various dosages NS, up 10 wt.-%, were examined. In addition, fly ash silica fume used as cement replacing materials, compare their influence on properties concret...
In this article, we submit the description of synthesis and identification of manganese(II) complexes with pyrogenic nanosilica-immobilized (d av = 10 nm; S sp = 290 m(2)/g) hydroxyaldimine ligands [Formula: see text]: salicilaldiminopropyl (L1); 5-bromosalicilaldiminopropyl (L2); 2-hydroxynaphtaldiminopropyl (L3); 2-hydroxy-3-methoxybenzaldiminopropyl (L4); 2-hydroxy-3,5-dichloroacetophenonimi...
Hybrid composites are characterized by a variety of properties that are of interest to automotive applications, including strength, mechanical, and thermal properties. In this work, palm kernel shell-filled maleated polypropylene composites and palm kernel shell/nanosilica-filled maleated polypropylene hybrid composites were produced using a Brabender Internal Mixer. The results showed that the...
In this research the effects of adding silica and alumina nanoparticles on flow ability and compressive strength of cementitious composites based on Portland cement were investigated. In the first stage, the rheological behavior of different samples containing nanosilica, nanoalumina and polypropylene, polyvinyl alcohol and polyethylene fibers were evaluated. With increasing of nanoparticles in...
The innovative properties of the nano materials can have advantageous application in the restoration and conservation of the cultural heritage with relation to the tailoring of new products for protection and consolidation of stone. Their potential use in this field needs to be assessed taking into account specific requirements such as effectiveness, harmfulness and durability. This paper repor...
Abstract— In recent days the demand for river sand is increasing due to its lesser availability. Hence the practice of replacing river sand with M-Sand is taking a tremendous growth. It is also inferred from the literature that replacement of normal sand with M-Sand produces no appreciable increase in compressive strength due to the variation in the pore size of concrete at micro level. This pa...
