Abstract: STRENGTH ENHANCEMENT USING STEEL AND POLYPROPYLENE FffiRE IN RECYCLED AGGREGATE CONCRETE ABSTRACT OF THE INVENTION The construction industry widely depends on natural aggregates, leading to depletion of natural resources and increased environmental impact due to construction and demolition waste. Recycled aggregate concrete (RAC) is an effective solution to promote sustainability by reusing construction waste materials. However, RAC generally exhibits reduced mechanical properties due to higher porosity and the presence of adhered mortar. To overcome these limitations, fibre reinforcement is introduced to enhance the performance of concrete. This study focuses on the strength enhancement of recycled aggregate concrete using steel and polypropylene fibres. Steel fibres are used to improve compressive and flexural strength by bridging macro-cracks and increasing load-carrying capacity, while polypropylene fibres help in controlling micro-cracks and improving ductility and durability. These materials contribute to the formation of additional Calcium Silicate Hydrate (C-S-H) gel, enhancing long-term strength and durability. The waste materials, which are otherwise disposed of in landfills, are processed and incorporated into concrete at controlled proportions. A water~ement ratio of 0.5 is maintained to achieve the required workability and strength. The primary objective of this study is to evaluate the effect of these sustainable materials on the carbonation depth and mechanical properties of concrete. The specimens are subjected to curing and tested for compressive strength and carbonation resistance. This approach not only helps in reducing environmental impact and waste disposal problems but also contributes to the development of sustainable and durable concrete.
