Study of sisal fibre reinforced concrete in lintels

Main Article Content


Concrete made with Portland cement has certain characteristics: - it is relatively strong in compression but weak in tension and tends to fail quickly when subjected to Tension. The deficiency in tension can be mitigated with conventional reinforcement & to some extent by the inclusion of a sufficient volume of Fibers. Change in the behavior of the Fiber – matrix composite after it has cracked, is due to the addition of Fibers (Balasubramanyan et al. 2015) Sisal Fiber is a promising concrete composite on account of its low density, less cost, increased specific strength and modulus, zero health risk, and it is easily cultivated in few countries including India. There has been an increasing interest in finding new applications for sisal-fiber which is traditionally used for making ropes, mats, carpets, fancy articles and others. The purpose of this research is to investigate the use of sisal fibers in concrete to enhance the mechanical characteristics of concrete and compare the differences in properties of concrete containing no fibers with fibers. The correlation on the effects of different type and geometry of fibers to the concrete is also the aim of the research. The scrutiny was carried out using several tests, which contained workability test, compressive test, split tensile test & flexural test. A total of ten mix batches of concrete containing 0%, 0.6%, 0.7%, 0.8% dosage of Fiber were cast. M25 grade concrete is considered for research as this grade is seen maximum consumption in industry.

Keywords: concrete, sisal fibre, resistance.
