Abstract

Nano technology application in concrete has added the efforts to improve its properties by altering the microstructure. Nano materials, by virtue of their very small particle size can affect the concrete properties. The use of nano silica of size 236 nm is study to improve the compressive strength of concrete. By replacing the cement with nano silica of 0.3%, 0.6% and 1% b.w.c experimental investigation has been carried out. The test shows a considerable increase in early-age compressive strength and a small increase in the overall compressive strength of concrete. With the increase in the percentage of nano silica, the strength increase was observed.
