Abstract

One of the major destruction of concrete in cold region is due to freeze and thaw cycles. Resistance to freeze and thaw cycles depends on high stress in concrete particularly when water in the pores of aggregates freezes. This leads to a volume change and resulting in more cracks in concrete and loss of durability. Nano-silica in the mix not only activates pozzolanic reaction but also acts as filler which in turn improves micro-structure of concrete paste. Use of glass fiber can help to bridge the gap initiated due to frost action [1]. In this study the effect of different replacement percentages of nano-silica with cement and fiber glass, and the number of freeze and thaw cycles on concrete strength was evaluated.
