Engineering College, Vallabh Vidyanagar– Gujarat – India 2 Abstract: India leading developing country in world. In future high strength high performance concrete required for construction work. So, utilization of artificial fibres in construction is required. The fibre like Polypropylene fibre, Steel fibre and Glass fibre are generally utilized in mortar and concrete. This research paper focused on fibre properties affected on concrete and mortar in the construction sector. Key words: Steel fibre, Glass fibre, Polypropylene fibre, Cost, utilization of fibre in construction area. INTRODUCTION: Natural fibers have been used for apparel and home fashion for thousands of years, with the use of wool going back over 4,000 years. In comparison, the man-made fiber industry began with the first commercial production of rayon in 1910. For those old enough to remember the 50's and 60's, this was when there was a great deal of technology happening in the man-made fiber industry. And the technology continues even today. Microfibers, fibers finer than the finest silk, were developed in 1989 and lyocell, was developed in 1993. Today, many man-made fibers, including polyester have been developed into beautiful fabrics that are being used by major designers. The concept of using fibers as reinforcement is not new. Fibers have been used as reinforcement since ancient times. Historically, horsehair was used in mortar and straw in mud bricks. In the 1900s, asbestos fibers were used in concrete. In the 1950s, the concept of composite materials came into being and fiber-reinforced concrete was one of the topics of interest. Once the health risks associated with asbestos were discovered, there was a need to find a replacement for the substance in concrete and other building materials. By the 1960s, steel, ISSN: 2231-5381 glass (GFRC), and synthetic fibers such as polypropylene fibers were used in concrete. Research into new fiber-reinforced concretes continues today. CRITICAL LITERATURE REVIEW: Dragica Jevtić, Dimitrije Zakić and Aleksandar Savić et at (2008) The addition of steel fibers in the amount of 60 kg/m3 (0.45% of volume), combined with admixture type superplasticizer, gave higher strength, both flexural and compressive, at all ages. Due to high mechanical strenghts and presence of silica fume, these composites can be successfully used, both in new construction and in repairs and reconstruction of already existing structures. P. Rathish Kumar and K. Srikanth et at (2008) There was no considerable change in compressive strength with optimum fiber addition but addition of fiber is effective in split tensile and flexural strength, with Glass fiber giving higher strength than Polypropylene fibers. The post peak strains are more for polypropylene based specimens as compared to Glass fiber based specimens, but they carried lower flexural strength. Mohammed Ezziane, Laurent Molez, Raoul Jauberthie and Damien Rangeard et at (2011) A study has been made of the mechanical behaviour of standard mortars, steel fibre mortar, polypropylene fibre mortar and a hybrid (Steel fibre + Polypropylene fibre) mortar, subjected to thermal exposure at 400°C, 600°C, 800°C http://www.ijettjournal.org Page 4311 International Journal of Engineering Trends and Technology (IJETT) – Volume 4 Issue 10 - Oct 2013 and 1000°C. The hybrid mortars appear to offer a good compromise: the polypropylene fibres reduce internal pressure that causes cracking during heat exposure and steel fibres limit cracking during the heat exposure and under subsequent mechanical loading. positive impact on shrinkage strain. Observation showed that nano-SiO2 apparently decreased the porosity of hardened cement paste and improved the microstructure of cement paste in dense and compact form. POLYPROPYLENE FIBRE: (PP FIBRE) Ahsan Habib, Razia Begum and Mohammad Mydul Alam et at (2013) They tried to show a comparative study on the mechanical properties of different fibers containing mortar composites. They also put emphasize on the fibers content and fibers length, because these are also important to contribute the mechanical strength of mortars similarly as type of fibers. Saidi M., Safi B., Benmounah A. and Aribi C. et at (2011) This study enabled us to see the influence of glass fibers short, long or mixed on the resistance and the mechanical behavior of the specimen of mortar, including the sequence of various stacking. M. Zhu and D.D.L. Chung et at (1997) Carbon fibers decreased the drying shrinkage of mortar. The drying shrinkage from 2 to 24 h is important, though it is usually neglected. Due to the drying shrinkage reduction, brick/brick joint strength was increased by adding carbon fibers to the mortar. The highest joint strength was attained at a fiber content of 0.5% by weight of cement. Sadrmomtazi and A. Fasihi et at (2010) From the investigation it appeared that utilizing PP fibers in cement matrix caused a slight enhancement in compressive and flexural strength. The contribution of further increase of the fiber content to mechanical strength was not positive. A possible reason for this observation could be the poor dispersion of PP fibers in mortar that increases pore volume and creates more micro defects in cement matrix. However utilizing high content of fiber (beyond 0.3%) had no ISSN: 2231-5381 Polypropylene is the first stereo regular polymer to have achieved industrial importance. The fibres from Polypropylene were introduced to the textile arena in the 1970s and have become an important member of the rapidly growing family of synthetic fibres. Today Polypropylene enjoys a fourth spot behind the “big three” fibre classes, i.e. polyester, nylon and acrylic. However, as opposed to other commodity fibres, its use as apparel and household textiles has been rather limited; the bulk of the fibre produced is used for industrial applications.

It does not absorb moisture. This means the wet and dry properties of the fibre are identical. Low moisture regain is not considered a disadvantage because it helps in quick transport of moisture as is required in special applications like babies‟ ever-dry nappies. PP construction / industrial fabrics Filling grade and staple fibre Substrate fabrics Non-woven needle punched 34 denier staple fibres It has excellent chemical resistance. PP fibres are very resistant to most acids and alkalis. The thermal conductivity of PP fibre is lower than that of other fibres and may be used in applications as thermal wear. DISADVANTAGES OF POLYPROPYLENE FIBRE: Low melting temperature which prevents it from being ironed like cotton, wool, nylon etc. Hard to be after manufacturing, except after substantial treatment and modification. Poor thermal stability which requires addition of expensive stabilizers to overcome this problem. Poor resilience compared to Nylon. Creeping due to its low Tem (-15 to -20°C), Poor adhesion to glues and latex.

It is a material made from extremely fine fibres of glass fibreglass is a lightweight, extremely strong, and robust material. Although strength properties are somewhat lower than carbon fibre and it is less stiff, the material is typically far less brittle, and the raw materials are much less expensive. Its bulk strength and weight properties are also very favourable when compared to metals, and it can be easily formed using moulding processes. Glass is the oldest, and most familiar, performance fibre. Fibres have been manufactured from glass since the 1930s.

Better effects were observed in flexural strength tests but the compressive strengths were significantly increased. There was no considerable change in compressive strength with optimum fibre addition but addition of fibre is effective in split tensile and flexural strength, with Glass fibre giving higher strength than Polypropylene fibres. A fibre mortar use for repair and rehabilitation work. It is use in concrete repair work by grunting. The fibre content and fibre length, because these are also important to contribute the mechanical strength of mortars similarly as a type of fibre. The fibre mortar increases the brick bond strength. Fibre mortar also increases the plaster strength and decrease the permeability. ISSN: 2231-5381 ACKNOWLEDGMENTS The Authors thankfully acknowledge to Dr. C. L.
