Abstract

In the detailed
study presented in this paper, an experimental study was conducted to
investigate the fresh concrete and compressive strength of concrete when fly
ash and silica fume were used. For compressive strength, concrete specimens at
three water - binder ratios, namely 0.35, 0.50, 0.70 made with various
combinations of portland cement, fly ash, and silica fume were tested at 7, 28
days, and 1 year. The effects of fly ash, silica fume, water - binder ratio,
and age were studied on produced 12 mixtures. From the test results, it was
concluded that the more effective variable on concrete’s performance was the
water - binder ratio; it decreases the compressive strength and unit weight of
the concrete.
