is paper describes an experimental study on the mechanical properties of high-strength fiber-reinforced concrete (HSFRC). e experimental parameters included the content and length of the steel fiber as well as the use of either a single-type fiber or hybrid steel fibers. e steel fiber contents were 1.0, 1.5, and 2.0% based on the volume of HSFRC, and the steel fiber lengths were 13, 16.5, and 19.5 mm. In addition, hybrid steel fibers incorporating steel fibers of different lengths were used. Compression tests and crack mouth opening displacement tests were performed for each HSFRC mixture with different experimental parameters. e mechanical properties of the HSFRC, such as compressive strength, elastic modulus, and tensile strength, increased with the steel fiber content. e mechanical property results of the HSFRC mixture using a single fiber length of 13 mm were greater than the results of the other mixtures. e compressive strength, elastic modulus, and tensile strength of the HSFRC mixture with hybrid steel fibers were similar to those of the mixtures with a single length of steel fiber. Additionally, based on the test results of the material properties, equations for predicting the elastic modulus and tensile strength of the HSFRC were suggested; the predictions using the proposed formula closely agreed with the experimental results.

“…Similar to normal weight concrete, addition of fibers to the lightweight concrete increases the load carrying capacity and control cracks [15]. It also increases the concrete resistance to dynamic and sudden loading, reduces crack width, increase tensile strength of concrete and its resistance against deformation [15][16][17][18]. Concrete technology now includes reinforcement in the form of polymeric fibers, steel fibers and glass fibers [15].…”

The present era is "THE ERA OF CONCRETE" because concrete is the most consumed material after water in developing countries. The huge demand of concrete requires large amount of cement which is the basic necessity for strength development of concrete. Large consumption of cement forces very high production to satisfy the demand. But production of cement produces CO2 in the atmosphere. One ton of cement produces about one ton of CO2 and hence it creates disturbance in natural global system. So, there is need of alternative materials which can replace cement. Previous researches shows number of materials such as Fly Ash, Silica Fume, and Sugarcane Baggase Ash etc may be used as a replacement of cement. India is second largest country which produce Sugar and hence sugar waste is also produced in very large quantity. Previous researches shows that Sugarcane Ash may be replaced by cement up to certain percentages. The higher percentage may lead the brittle failure of Concrete which may be overcomed by the addition of Steel Fiber and good range Super plasticizer to get Self Compacting nature of Concrete. Here an attempt is made to collect the detailed research overview for Sugarcane Baggase Ash as a replacement of cement along with the separate study of Steel Fiber reinforced Concrete. This would be helpful for fiber reinforced concrete using alternative materials.

The aim of the presented research programme was to investigate the flexural behaviour of steel fibre reinforced self-compacting concrete beams. The tested beams were reinforced with two types of crimped steel fibres. Fibres were added in volumes of 0.5, 1.0 and 1.5 %. The experimental tests were conducted on specimens cut from 1.2 m long elements. Before destructive mechanical testing the specimens were subjected to medical X-ray computed tomography (XCT) procedures. Results of XCT allowed to determine the distribution of fibres. The flexural behaviour of the beams was tested according to the RILEM TC 162-TDF recommendation. A comparison of non-destructive results and mechanical behaviour of tested specimens proved a very strong dependence. XCT also made it possible to assess the uniformity of fibre distribution throughout the tested elements. The influence of the location of concrete casting on fibre distribution was determined. The influence of mixture flow on fibre orientation was also analysed.
