ABSTRACT: This paper investigates
the experimental results on the effect of nano silica fume on compressive
strength development of concretes containing high volume fly ash (HVFA). The
effect of various silica fumes contents such as 1%, 2% & 3% (wt. %) as
partial replacement of cement on the compressive strength of cements is
evaluated in the first part. The nano silica fume content which exhibits the
highest compressive strength above is used in high volume fly ash concretes
containing 30% and 50% class F fly ash. The results show that among three
different silica fumes contents, the addition of 1% increases the compressive
strength of concretes. The addition of 1% silica fume also increases the early
age and 28 days compressive strengths of HVFA concretes.
