The Use Of Micro-Silica To Improve The Compressive And Flexural Strength Of Concrete
In present era vast development occurred in the field of concrete technology. Many research scientists and
research fallows have been developed numerous techniques to improve the strength & durability parameters of the concrete.
This present research work is mainly focused on one of such method in which silica fume is used to improve the
compressive and flexural strength of concrete. It gives the brief information regarding how exactly silica fume affects
strength and durability parameters like compressive strength, flexural strength of concrete. Various samples of M20 grade
concrete were taken with water cement ratio as 0.5 to show the effect of silica-fume additions as 0%, 7.5% and 10% of
binder replacement. The results show significant increase in compressive and flexural strength of concrete up to certain
percentage of silica fume addition.
