Abstract: Over the past 35 years a significant amount of research has been performed in the FRC field. Today many different FRC composites have been commercialized around the world. However, the technical aspect of FRC system remained essentially undeveloped for several centuries.
Slurry infiltrated fibrous concrete (SIFCON) was first produced in 1979 in the USA, by incorporating large amounts of steel fiber in moulds to form very dense network of fibers. The network is then infiltrated by fine liquid cement-based slurry. Since it is not possible to use more than 2% of fiber in FRC (fiber reinforced concrete) because of workability and mixing issues, SIFCON is applied to contain fiber amount as high as 12%. Having higher mechanical properties in both strength and durability is one of the advantages of SIFCON in comparison with FRC. In view of the above, the objectives of this study are focused mainly on investigating the strength characteristic properties.
The study has been carried out on fibers having aspect ratio of 50 and The cement-sand slurry used is of the proportion 1:1 with a water cement ratio 0.45. The percentage of fibers (by volume fraction) used in the experimentation is 1% SF, 1%HDPEF & 1%WPF by the volume of concrete.
This study showed that 1% addition steel fiber volume shows greater strength in compressive and flexure strength test. Use of 1% WPF and HDPEF gives optimum result in the shear and tensile strength test respectively.
The result obtained indicated that different fibers behave differently in compressive load, flexural load, and tensile load and shear load. Because the bonding strength between the fiber matrix and concrete layer will varies for different fibers. However the SIFCON made with the highest possible fiber volume fractions shows the best results.
