&#; This paper represents the results of an experimental work on some properties of M25 grade of concrete containing different levels of silica fume. Silica fume is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production. A certain percentage of silica fume as a cement replacement, can improve some properties of high-strength concrete such as compressive strength, flexural strength durability etc. The main objective of this study was to determine the optimum percentage of silica fume to replace cement in order to improve the properties of hardened high-strength concrete. To fulfill the objective, some properties of concrete containing silica fume were evaluated after 7, 14 and 28 days of immersed curing. Furthermore, comparison between regular concrete and silica fume concrete containing different levels of silica fume content (5%, 10% and 15%) was conducted. The water/binder ratio was kept constant at 0.43 throughout the mixing process. The results of this research work indicate that compressive strength and flexural strength exhibited the highest improvement with 5% and 10% silica fume replacement respectively. This paper can be a useful source of information for other researchers to understand the benefits and adverse effects of silica fume and have an overview of its optimum percentage when dealing with concrete.

85% Densified Silica Fume is a micro-silica fume with 85% SiO2 content, and the Bulk density is 550-700kg/m3.
The main component of silica fume is SiO2, with a small amount of impurities such as C, Fe2O3, K2O, CaO, Na2O, etc. Due to its inherent characteristics, the average particle size is 0.23 um, the specific surface area is 20 m2/g, and the sieve residue of 45 um is less than 3%. By adding silica fume into concrete, the compacting, impermeability, corrosion resistance, frost resistance and other properties of concrete can be greatly improved. In concrete, the amount added is 5-10% of the cement content.
Introducing our top-quality 85% Densified Silica Fume, a game-changer in the construction industry. This highly effective concrete additive is designed to enhance the physical properties and longevity of concrete structures, making it an essential component for demanding construction environments.
