Modelling of nano-silica in cement paste

SPIE Proceedings, 2013
Recently published experimental evidence shows that nano-silica is a material that can be used to enhance the strength and durability characteristics of concrete. Engineered concrete at the nano-scale is achieved through the integration of nano-materials in suitable proportions and relevant mixing methods. Being a pozzolanic and reactive material along

Effect of Micro/Nano Silica Particle Feeding for Mice

Journal of Nanoscience and Nanotechnology, 2008
The toxic effect of nano and micron sized silica particle was studied on mice. The size of the nano and micron sized silica were approximately 30 nm and approximately 30 microm, respectively. The mice, Balb/c (20 approximately 30 g, white) and C57BL/6J (black) for the experiment were classified to normal, nano sized silica (1%), and micron sized silica

Effect of nano‐silica on the mechanical, thermal, and crystalline properties of poly(vinyl alcohol)/nano‐silica films

Journal of Applied Polymer Science, 2012
AbstractPoly(vinyl alcohol)/nano‐silica (PVA/nano‐SiO2) films were prepared through extrusion blowing with the addition of water and glycerin as plasticizer. The characteristic properties of PVA/nano‐SiO2films were investigated by differential scanning calorimetry, dynamic mechanical analysis, Haake torque rheometry, and atomic force microscopy (AFM ...

Performance Evaluation of Nano-silica Modified Bitumen

2015
In this study, different contents of Nano-silica, 2 wt.%, 4 wt.% and 6 wt.%, have been added to bitumen to modify the physical, mechanical and rheological properties of warm mix asphalt (WMA). WMA is containing 2 wt.% of Sasobit (mixture of long-chain hydrocarbons).

Application of nano-silica in concrete

2012
This report presents the achievements of the 2012 third quarter focusing on the application of nS in concrete. In this context, nano-silica precipitated from the olivine dissolution in acid (OnS) and nano-silica sludge (nSS) were used for the experimental work.

Nano-Macro Correlation of Nano-Silica Concrete

Concrete mixes using progressively finer size nano-silica particles (7–150nm) were prepared to study the effect of nano-size pozzolans (nano-silica). Conventional compression tests demonstrated progressively higher strength with finer size of the nano-silica down to 12nm particle size.

Preparation of Nano-silica and Nano-silicone

Scientific Journal of King Faisal University: Basic and Applied Sciences
In this research, silica and silicon were prepared using glass waste. The preparation process consisted of several stages that started with the collection of crushed glass samples, treating them physically (grinding and granular sorting) and mixing granulated crushed glass with NaOH at ratios of 1:1, 1:2 and 1:3.
