Cement is utilized extensively in the manufacturing of concrete, which makes it most common material used building construction. However, usage a great deal cement results CO2 emissions, leads to greenhouse effect. Numerous studies have developed use nano-SiO2 concrete materials lower content mixtures while improving mechanical properties. Additionally, number demonstrated that silica NPs trigg...

By J. BURNS AND P. B. NEAME T lIE PERIODIC ACID-SCHIFF (PAS ) REACTION is generally accepted as the method of choice for demonstrating glycogen in blood cells. This reaction depends upon the presence, in glycogen, of vicinal glycols which are oxidized by periodic acid to dialdehydes. The latter are subsequently condensed with Schiff’s reagent to produce a magenta-red product, visible by light m...

Biosilicification sets the standard for the localized in vitro precipitation of silica at low orthosilicate concentrations in aqueous environment under ambient conditions. Numerous parameters must be controlled for the development of new technologies in designing inventive nanosilica structures, which are able to challenge the biological templates. A long neglected requirement that came into fo...

In this study two series of self compacting concrete mixtures were prepared with 100% coarse recycled concrete aggregates and different percentages of 0%, 20%, 40%, 60%, 80% and 100% fine recycled concrete aggregates. In series I and II the water to binder ratios were 0.50 and 0.45, respectively. The cement content was kept 350 3 m kg for those mixtures that don't have any Nano-Silica. To impro...

The particle growth of silica below the isoelectric point plays a key role in oil well cements, production of silica gels and production of nanosilica by dissolving silicates. In this article, we study the particle growth of silica below the isoelectric point using olivine, a silicate mineral, and sodium silicate solutions as silica sources in acid, where the particle size, soluble silica conce...

The temperatures of standard glassware and ceramics are nearly impossible to tell just by sight. Therefore, burns from touching heated surfaces are common in the laboratory and in the kitchen. The sol-gel process is a safe method to create foam under ambient conditions. Adding different chemical compounds causes the foam to have varying physical and chemical characteristics. This project focuse...
