Influence of Nano-Silica and Silica Fume in the Steel Corrosion Embedded in Concrete

Corrosion of steel is one of the most important potential dangers and threats in concrete structures. Corrosion of steel embedded in reinforced concrete plays a key role in reducing the strength and durability of reinforced concrete. Several studies have proposed that alternative approaches to enhancing the performance of reinforced concrete and its resistance to corrosion. In this study, the r...

INFLUENCE OF NANO SILICA ON PROPERTIES AND MICROSTRUCTURE OF HIGH ALUMINA ULTRA-LOW CEMENT REFRACTORY CASTABLES

Colloidal silica bonded refractory castables have been developed recently. It was found that colloidal silica is one of the best binders can substitute other binders such as cement in No Cement Castable (NCC) and Ultra Low Cement Castable (ULCC) refractories. Also composition of colloidal silica with appropriate additives resulted in a gel form which makes the initial strength. Moreover, the na...

Effects of Sand and Silica Fume on the Vibration Damping Behavior of Cement

The addition of sand to cement paste was found to degrade the vibration damping ability, as shown by decreases in both loss tangent and storage modulus under flexure. However, further addition of silica fume more than restored the vibration damping ability, due to the silica fume causing increases in both loss tangent and storage modulus. Silica fume increased the loss modulus of mortar by as m...
