Mechanical Characteristics of Fiber Reinforced Self Compacting Mortars (FRSCM)

In modern day construction practice, repair and rehabilitation of structures has taken aprominent role. Mortar plays a vital part in these works. As such, the flowability of mortarcan be an added advantage when inaccessibility comes into picture like in case of congested reinforcement or narrow cracks or fissures. Due to the application easiness and mechanical advantages, Self Compacting Mortar is preferred for repair purposes especially in reinforced concrete structures these days. The cement as well as the ingredients of the paste, mineral admixtures (pozzolanic or inert nature) and plasticizing chemical admixtures should be carefully chosen in order to obtain a suitable paste composition to enrich the granular composition of the mix. There is no universally accepted agreement on the effect of these factors due to the complexity of combined action; thus, it is hard to make a generalization.The objective of the study is to evaluate the effect of fiber and mesh in Self CompactingMortar from the viewpoint of fresh state behaviour and mechanical performance. For thispurpose two fibers (Polypropylene and Glass fiber) and two types of mesh (Chicken meshand G.I. wire mesh) were used. The results of 54 panels, 54 cubes and 54 cylinders forflexure, compressive strength and split tensile strength are presented.
