“…The best dimensions (length/diameter) of straight steel fibers were 30/0.5 and 10% in volume achieved better value for flexural strength [46]. Sonebi et al (2005) [47] concluded that a matrix incorporating fly ash or silica fume offers greater strength than a plain matrix. Silica fume gives higher strength in compared with fly ash.…”

Conventional concrete is categorized as brittle. As a result, researchers continued working to develop it into a substance having ductile characteristics. Concrete showed remarkable improvement when fiber was incorporated at a ratio of 1-2%. Slurry-infiltrated fiber concrete (SIFCON) allows for the use of up to 20% more fiber when combined with unique cement slurry. Concrete that was produced had increased strength and ductility. The influence of slurry and fiber forms with different volumes on the resistance of concrete to compression, flexural, shear, and bond was the main focus of this review study. The outcomes of several previousinvestigations revealed a significant relationship between the strength of concrete and the slurry mixture, fiber type, and fiber volume. Additionally, it was shown that the majority of research all agreed that certain methods should be followed when employing a volume of more than 5% fiber. These processes entail employing fine-sand less than 1 mm in size to create a suitable cementslurry and replacing up to30% of the cement with fly ash (FA), silica fume (SF), and metakaolin to create a cement slurry capable of penetrating interlocking with fiber of all forms and volumes

“…Khatri et al (1995) [37] found that the addition of 10% silica fume to concrete reduces both the initial and final setting times by at least one hour. 1.6.Slump Experiments showed that compared to normal concrete, slump of silica fume concrete decreases as the SF replacement of cement increases up to 15% under different water-binder ratio (Jahren (1983) [38] , Safwan et al, 1994 [39] ; Kwan, 2000 [40] , Sonebi et al, 2005 [41] ). 2007) [42] .…”

Silica fume (SF) modifies interfacial transition zone between cement paste and aggregate at the micro level. Properties of both fresh and hardened silica fume concrete are affected significantly compared to normal concrete. Experiments indicate that concretes become more cohesive and less prone to segregation in the presence of silica fume, moreover, performance of water demand, setting of time, plastic shrinkage varies respectively from concretes without silica fume. Obvious mechanical enhancement of concrete is observed in the aspects of compressive strength tensile strength, elastic modulus as well as fracture toughness.

This research aims to shed light on the fire flame effect on some mechanical properties of SIFCON samples, such as compressive strength, flexural strength and modulus of elasticity and comparing the results with CEN design curve and CEB. Higher temperature resistance is one of the most important parameters affecting the durability and service life of the material. This study comprised of casting and testing SIFCON specimens with 6% fiber volume before and after exposure to elevated temperatures. Two fire exposure duration of 1 and2 hours were investigate. In addition to room temperature, Silica fume was used as a partial replacement (10%) by weight of cement. It was found from the results achieved that after exposure to high temperatures, compressive strength, flexural strength and elastic modulus decreased. The drastically reduction of compressive strength took place with increasing temperature. The residual compressive strength, flexural strength and elastic modulus at 1010 °C were in the range of (58.4 to 80.1%), (81.6 to 78.7%) and (30.4 to 32.8%) respectively. The compressive strength test results of this study together with results obtained by other investigators were compared with CEB strength-reduction curve and that of CEN. It was noticed that the test results agreed with CEN design curve rather than with that of CEB.
