The main objective of this work is to study the behaviour of SIFCON produced by partial replacement of cement with glass powder. Slurry Infiltrated Fibrous Concrete (SIFCON) is a special type of fibre reinforced concrete (FRC) which have large amount of fibre. FRC contain fibre only 2% to 5% by volume of cube because of balling and clustering problem but in SIFCON we can use fibre from 5 to 20 % of volume of cube. Waste glass contain high silica (SiO2) due to which when these waste glass is ground to very fine powder react with alkalies in cement and form cementitious product that help in strength contribution. Further in this research work we are going to use 6%, 12% and 18% of steel fibre by volume of 150mm× 150mm× 150mm cube to find out the optimum strength and compare it with the strength of SIFCON produced by partial replacement of cement with glass powder at the days of 7days, 14days &28 days. This research therefore is a study of the performance of the SIFCON concrete made of 6%, 12% & 18% of steel fibre from which optimum fibre content was obtained and then by using this volume of fiber, behaviour of SIFCON produced by partial replacement of cement with glass powder were studied. In this work 5%, 10%, 15%, 20% and 20% Glass powder is replaced by weight of cement. Based on this study compressive strength versus percentage of replacement of Glass powder curves have been plotted. Index Terms-fibre reinforced concrete, Glass Powder, replacement of cement, SIFCON.

SIFCON, as a type of fiber reinforced concrete (FRC), has a unique and superior properties in the areas of both ductility and energy absorption and the impact resistance is recognized as one of the significant properties of SIFCON. The main object of present study is to determine the influence of SIFCON mortar type and fiber volume fraction on the behavior of SIFCON under impact loading. For SIFCON mortar, supplementary cementitious materials [Class F fly ash (FA) and silica fume (SF)] were used as a partial replacement by weight of cement. The percentage of FA replacement was (20%) and of SF replacement was (10%). Hooked end steel fibers were used with different fiber volume fraction (6, 8.5, and 11) %, the test was carried out using disc specimen (152 mm diameter by 63 mm thick). The test results were compared with those of fiber reinforced mortar (FRM) containing 2% fiber volume fraction, as a reference (control) mix. The test results show that in general, there is a significant improvement in impact resistance of all SIFCON mixes with increasing fiber volume fraction. SIFCON mix containing SF and FA and 11% volume fraction exhibited the highest impact resistance, and the energy required for completing failure was increased by 11.87 times, when compared with the control mix at 90 days.

SIFCON is a high strength fiber reinforced concrete which has high ductility, crack resistance and impact resistance. SIFCON is produced by a process in which fibers are put into an empty mould, after which the fiber mass is infiltrated by a slurry. An experimental program is conducted in order to study the behavior of SIFCON by using M-sand and partially replacing cement with silica fume. Strength tests were conducted to study the mechanical properties of SIFCON. Non-destructive tests such as Rebound hammer and Ultrasonic pulse velocity tests are also performed.

Slurry infiltrated fibrous concrete (SIFCON) is a new and unique type of high performance concrete invented by Lankard in 1979, containing high percentage of fiber about 6% to 20% by volume. SIFCON possesses high strength as well as large ductility and has excellent potential for structural application. The matrix in SIFCON has no coarse aggregate but high cementitious content. The aim of study is to evaluate the performance of SIFCON mortar with lower fiber percentage and to minimize the fine aggregate usage by replacing it with industrial waste i.e. steel slag. Thereby, it also helps in effective disposal of industrial waste and helps in mitigating environmental pollution. The main objective of this study is to determine the effect of partial replacement of sand with steel slag on the mechanical properties of SIFCON mortar. The experimental program was carried out with 2%, 3% and 4% of fiber content by volume combined with replacement of sand by steel slag in proportion of 10% and 20% by weight. For this purpose, compressive strength, flexural strength, split tension and impact strength of SIFCON specimens were tested after 7 and 28 days of curing, yielding positive results.

Concrete is a composite material which has wider application in construction industry because of strength and durability.The construction of long span bridge, high rise building, offshore structures, and other mega structures requires materials, with increasingly improved properties, particular strength, stiffness, toughness, ductility, durability. In the cause instances, simultaneous improvement in a combination of properties is needed. Such material often called “High Performance Materials” and “Advanced Materials” and they are basically different from other conventional materials The aim of present investigation is to study a Slurry Infiltrated Fiber Reinforced Concrete (SIFCON), properties. SIFCON possesses the high strength as well as large ductility because of its high tensile strength.In this experiment cement, sand, fly ash is kept in constant value. The steel fiber are added in various proportions, i.e. 6%, 8%, 10%, 12% to arrive the optimum percentage.

The study deals with the effect of using Slurry infiltrated fiber concrete (SIFCON) with the reinforced concrete beams to explore its enhancement to the flexural capacity. The experimental work consists of the casting of six beams, two beams were fully cast by conventional concrete (CC) and SIFCON, as references. While the remaining was made by contributing a layer of SIFCON diverse in-depth and position, towards complete the overall depths of the built-up beam with conventional concrete CC. Also, an investigation was done through the control specimens testing about the mechanical properties of SIFCON. The results showed a stiffer behavior with a significant increase in load-carrying capacity when SIFCON used in tension zones. Otherwise high ductility and energy dissipation appeared when SIFCON placed in compression zones with a slight increment in ultimate load. The high volumetric ratio of steel fibers enabled SIFCON to magnificent tensile properties.
