“Application of Silica Fume and Nanosilica in Cement and Concrete – A Review”

Abstract

This paper reviews the current status of silica fume (micro silica), the application of nano-silica and
programs for sustainable development and the recent development of the concrete industry. In addition to this, as well
as to conserve energy and resources, to protect the environment and reduce the waste. This contradiction is very
limited work on the impact of paste, mortar and concrete, and what the complete use of silica nano-micro silica that
can be developed mechanical strength and durability characteristics. It has been studied to understand the impact of
micro-and nano-silica in a variety of literature paste, fresh and enhance the fine characteristics of the cement mortar
and concrete. It utilizes a nano-structure and microstructure characterization tools and materials, micro-silica nanosilica is a separate optimum use of the time to create a new concrete mixture that occurs in concrete, long-lasting in
the future.
