“…Employing fibers in concrete and cement-based composites, in order to increase toughness and ductility in post-crack regions, have seen considerable growth. The collapse and destruction of concrete is highly dependent on macro-or micro-crack formation under loading or environmental effects [11][12][13][14][15]. Thermal and humidity changes in cement paste lead to micro-crack formation that concentrates on coarse aggregate surface.…”

Concrete shrinkage and volume reduction happens due to the loss of moisture, which eventually results in cracks and more concrete deformation. In this study, the effect of polypropylene (PP), steel, glass, basalt, and polyolefin fibers on compressive and flexural strength, drying shrinkage, and cracking potential, using the ring test at early ages of high-strength concrete mixtures, was investigated. The restrained shrinkage test was performed on concrete ring specimens according to the ASTM C1581 standard. The crack width and age of restrained shrinkage cracking were the main parameters studied in this research. The results indicated that the addition of fiber increases the compressive strength by 16%, 20%, and 3% at the age of 3, 7, and 28 days, respectively, and increases the flexural toughness index up to 7.7 times. Steel and glass fibers had a better performance in flexural strength, but relatively poor action in the velocity reduction and cracking time of the restrained shrinkage. Additionally, cracks in all concrete ring specimens except for the polypropylene-containing mixture, was developed to a full depth crack. The mixture with polypropylene fiber indicated a reduction in crack width up to 62% and an increasing age cracking up to 84%.

“…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].…”

“…Self compacting concrete (SCC) is defined as a concrete that has excellent deformability and high resistance to segregation and can be filled in heavily reinforced or restricted area without applying vibration [2,3,4,17]. SCC was developed in Japan in the 1980, and recently this concrete has gained wide use in many countries for different applications and structural configurations [2,3].…”

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.

“…Among these is the Normal-weight Fiber Reinforced Concrete (NWFC), which is developed after addition of fibers of various shapes and material. Effectiveness of fibers in crack control and for improving mechanical properties like flexural performance, bond, toughness and as an alternate to minimum shear reinforcement for concrete in highly congested reinforcing areas is already well acknowledged and reported [1][2][3][4]. Also in recent years tests on using steel fiber reinforced concrete as strengthening material have shown promising results [5,6].…”
