Abstract
With the development and modernization of societies, lot of construction activities are seen everywhere. These construction activities are increasing at faster rate by large amount. Also, the destruction of existing structures, which have reached their service life, runs parallel to the construction activities. It is not essential that the structures need to be demolished only after when they have completed their service life, but also due to change in fashion and ongoing trend of reconstruction of even healthy structures just for creating more space in order to meet the present demand. All such activities are generating waste in bulk, and this waste is called the Construction and Demolition (C&D) waste. Disposal of such C&D waste in a sustainable manner is a hard nut to crack for the builders, developers and owners. While the disposal of C&D waste is a challenge, on the other hand there is a severe shortage of naturally available aggregates for construction of structures. Reduction of this demand in a small way is possible with the recycling or reusing of construction and demolition waste generated from the construction activities. Hence, the recycling of demolished waste is a sustainable solution of C& D waste. Recycled concrete aggregate have limited application as fill and sub grade material below foundation of structures, pavement etc. these applications are non-structural applications. However research has been ongoing all over the world especially in Japan, China, European countries and some part of India also, from last 50 year in order to find the potential implement of recycled aggregates as a structural grade concrete. The research work on “Strength and Deformation Characteristics of Fiber Reinforced Concrete made with RAC” is presented here and is one such attempt to establish the RAC as a structural grade concrete. This research work focus on mainly four structural properties of concrete i.e. Compressive Strength, Split Tensile Strength, Flexural performance and Flexural toughness. In this present study the experimental part is divided into two different series viz. Series-A (without fibers concrete mix) and Series-B (1% by volume Steel fibers in concrete mix). The natural coarse aggregates are replaced with Recycled coarse aggregates at different replacement ratios. Four replacement ratios are considered in this present study 0% (control specimens), 20%, 40% and 80% M-20 grade of concrete mix is considered in this study. In order to predict the flexural performance of RAC, 16 reinforced concrete beam specimens were prepared. The section was designed as under-reinforced section and tested on UTM for flexural behaviour under two point loading. Based on the results obtained it is found that on addition of steel fibers there is increase in almost all the structural properties of normal concrete and concrete made with recycled aggregates. The investigation indicated encouraging results for RAC beams, cube and cylindrical specimens in all respect, thus pointing to recycled aggregate concrete as potential alternative structural grade concrete of the 21st century
