Abstract

In india brick masonary is very common Structure built with brick units bonded together by mortar .Brick usually having a higher strength and stiffness compared to mortar. Further mortar is usually cementitious material having little tensile strength and showing brittle behavior. Use of suitable reinforcement in mortar could significantly enhance the performance of brick masonry for crack, shear, bond, compression, toughness and resistance. The aim of this paper is to analyze the improvements in the strength of mortar by using fiber. By performing appropriate experiments, an attempt was made to analyze the properties of fibre reinforcement mortar and its application in masonary work. An attempt was made to cast the cement sand mortar with a mixture of fibres in different volume and observing its compressive and tensile strength. The shear and compression bond tests were performed at different mix proportion of fibre reinforcement prepared units made with FRM and plain mortar .The tests were carried out according to ASTMC 780 and Indian specifications. After addition of fibre in mortar the compressive, tensile strength increases and toughness also increases and ultimate deformation decreases. The cost of Fibre reinforced masonry is slightly more than plain mortar but it was felt that FRM Unit has better crack propagation so it becomes a good alternative of earthquake resistant building in which simple mortar is used.
