The effect of size and replacement content of nanosilica on strength development of cement treated residual soil (vol 118, pg 294, 2016)

•Strength development of the treated residual soil were improved by nano silica.•Compressive strength of the soil increased under effect of nano silica.•CEC and ER of treated soil increased when nano silica was added.•C-S-H gel of cement treated soil increased when nano silica was added.
