Strength and Permeability Characteristics of Fibre Reinforced Recycled Aggregate Concrete with Different Fibres
Utilization of recycled aggregates in the production of concrete is now given lot of emphasis as it is viewed as an effective waste management practice, which can substantially contribute for the reduction of environmental deterioration. At the same time this is a cost effective technology saving natural resources. Recycled Aggregate Concrete (RAC) is now being used in many sectors of the construction industry. Though, lot of research has been reported on RAC, very little information is available about the effect of using recycled aggregate in the production of Fibre Reinforced Concrete (FRC). This paper presents the results of experimentation conducted to evaluate the strength and permeability characteristics of FRC produced with recycled coarse and fine aggregates. Three types of fibres viz., steel, glass and polypropylene were used in the production of FRC. Compressive, tensile, flexural and shear strengths of Fibre Reinforced Recycled Aggregate Concrete (FRRAC) have been evaluated from the experimentation. Chloride ion permeability has been determined as measure of permeability of FRRAC. The results of the study show that recycled coarse and fine aggregates can be successfully used in production of fibre reinforced concrete.
