“…Based on an extensive body of research data available in the literature on concretes containing pozzolanic materials, there is a general agreement that the best performing mixtures typically incorporate ternary or quaternary cementitious blends rather than just a single mineral admixture (Bleszynski et al 2002, Hooton and Titherington 2004, Mehta and Gjørv 1982, Toutanji et al 2005. In particular, a combination of cement, fly ash and silica fume has been suggested to be very promising for bridge decks applications .…”

IntroductionConcrete bridge decks are inherently exposed to harsh environment. They are known to undergo degradation due to numerous distresses, of which the most common are corrosion of reinforcement (caused by ingress of chloride through bulk concrete), freeze-thaw damage, shrinkage cracking (aggravating both corrosion and freeze-thaw problems) and surface scaling due to deicing salts.Recently, high performance concrete (HPC) has become widely utilized in the applications where severe environment leads to premature deterioration. The premise behind the development of HPC was to address the durability issues typical of normal concrete. HPC almost always implies incorporation of mineral admixtures, such as fly ash (FA) or silica fume (SF). These materials are added to concrete for variety of reasons, of which the most important is improvement (compared to plain ordinary portland cement (OPC) concrete) of certain durabilityrelated properties. However, there are also some downsides of utilizing them in concrete. For example, fly ash is known to reduce the early age strength and early age resistance to chloride-ion penetration, as well as resistance to salt scaling and carbonation. Furthermore, fly ash concrete has been reported to be fairly sensitive to curing conditions compared to plain cement concrete. The shortcomings of incorporating silica fume, on the other hand, include increased susceptibility to shrinkage cracking and potentially reduced resistance to freezing and thawing.In the view of the aforementioned side effects associated with the use of fly ash or silica fume in binary mixtures, the ternary cementitious systems have been introduced as a potentially viable solution to address those durability issues. Superior properties of this kind of cementitious systems are commonly attributed to so-called synergistic effect taking place when both pozzolanic materials are utilized. The intuitively obvious benefit of the use of OPC/FA/SF mixtures is that the presence of fly ash in concrete compensates for the deficiencies of silica fume, and vice versa. For example, FA offsets the increase in water demand, heat of hydration and alkalinity of pore solution resulting from addition of SF. On the other hand, SF compensates for the low early age strength and sensitivity to curing (with respect to development of both mechanical and durability-related properties of FA concrete). From the economical perspective, a relatively low cost of FA counterbalances higher cost of SF. Although a fairly large amount of research has been conducted to evaluate the properties of ternary cementitious mixtures containing fly ash and silica fume, relatively little was done with the emphasis on the durability-related issues encountered when these binder systems are used in the bridge deck concrete. Up to date, no data exists on the actual performance of ternary concrete containing class C fly ash and silica fume in bridge decks.The purpose of this research was to examine the applicability of ternary binder systems containing ordinary port...

“…Using silica fume, which was used in production of silicon metal or ferrosilicon alloys, increased strength of concrete and reduced its permeability [9]. Silica fume also reduced water / cement ratio in cement and helped to obtain impermeable internal structure in concrete [10]. At the same time, there were further studies for the conversion of incised old asphalt to new asphalt by specific technologies [11] for the usage in the road constructions and usage of boron production related wastes in the construction sector [12].…”
