In this study, the usability of the quartz and basalt rocks as aggregate in Slurry Infiltrated Fiber Concrete (SIFCON) has been examined. In the study, quartz aggregate has been taken as reference and basalt aggregate has been used as a substitute and separately. The aggregates have been ground and classified in the dimensions of 0-0.1 mm (powder) and 0.1-0.6 mm (sand). The physical properties of the aggregates have been determined and SIFCON slurry has been prepared. The samples produced by this slurry have been conducted to Compressive Strength, Flexural Tensile Strength, Fracture Toughness, Ultrasonic Pulse Velocity, Schmidt Hammer tests. Moreover, unit cost has been examined with the different aggregate usages. Consequently; the highest compressive and flexural strength being respectively 99.75 MPa and 32.01 MPa have been reached with the use of quartz aggregate. The compressive strength of the basalt aggregate is 14% lower than that of the quartz aggregate where, its flexural strength almost remained in the same value. It has been observed that basalt aggregate is more economical in terms of unit strength cost. It is suggested that basalt aggregate could also be used in SIFCON as an alternative to the quartz aggregate.

“…Thus, using fiber in concrete, which increases both the flexural strength and the energy absorption capacity, is one of the best resolutions for the brittleness issue. However, as the amount of fibers in the mixture increases, the workability of the concrete is adversely affected, therefore the proportion of fiber that can be added to the concrete is generally 1-3% (İpek et al, 2012;İpek et al, 2014;Hajar et al, 2004) Nevertheless, there are various special composites, such as slurry infiltrated fiber reinforced concrete (SIFCON), that are produced with a higher steel fiber volume ratio (Wang, 1994). SIFCON, which was produced by Lankard (1984), is a composite that contains high rate fiber and a cement based slurry with superior mechanical properties such as high compressive, tensile, shear, flexural and toughness values Homrich & Naaman, 1987;Naaman et al, 1992a).…”

In this study, the effect of curing conditions on the mechanical properties of slurry infiltrated fiber reinforced concrete (SIFCON) was investigated. For this purpose, SIFCON samples containing 4% and 8% steel fiber with two different aspect ratios were produced. The samples were subjected to three different curing types, namely standard, dry and accelerated curing methods. Ultrasonic wave velocity, flexural strength, fracture toughness, compressive strength, impact resistance and capillary water absorption tests were performed on the samples. The highest flexural strength was found to be achieved in the samples with an aspect ratio of 55 and a content of 8% steel fiber. The most suitable curing method was determined as the standard curing method and the best flexural strength was achieved at the rate of 8%. According to the test results, the best strength properties were achieved in the samples exposed to the standard curing method. In addition, the samples exposed to the accelerated curing method showed satisfactory values. The accelerated curing method can be used as an alternative in SIFCON production especially in applications requiring mass production.

This paper reports on a wide-ranging study on the properties of slurry infiltrated fiber concrete containing fly ash, Metakaolin, and hook ended steel fibers. Properties studied include workability of fresh slurry infiltrated fiber concrete, and compressive strength, flexural tensile strength, splitting tensile strength, dynamic elasticity modulus, impact energy of hardened slurry infiltrated fiber concrete. Fly ash and Metakaolin content used was 0%, 2.5%, 5.0%, 7.5% and 10% in mass basis, and hook ended steel fibers volume fraction was 0%, 2.0%, 3.0% and 4.0% in volume basis. The laboratory results showed that steel fiber addition, either into control concrete or fly ash, Metakaolin blend slurry infiltrated fiber concrete; improve the tensile strength properties, flexural strength, impact energy and modulus of elasticity. In this experimental study, compressive strength improvement ratio is 33.60%, and Structural efficiency is 9.50 % higher in slurry infiltrated fiber-concrete with Metakaolin as compared with fly ash based slurry infiltrated fiber concrete at the 4% replacement ratio of hook ended steel fibers by volume.
