Abstract - Recycled cellulosic pulp, derived from recycled
friendly concrete by incorporating recycled materials significantly lowers its environmental impact, supporting sustainable construction efforts.
paper waste and agricultural by-products, offers an ecofriendly alternative for concrete reinforcement. This sustainable material leverages its natural fibrous structure to potentially improve the overall performance of concrete while reducing environmental waste. Its inclusion in concrete formulations serve a dual purpose: enhancing material properties and contributing to greener construction practices. In this study, we developed several concrete mixes by varying the amount of recycled cellulosic pulp and focused on assessing three key properties: compressive strength, split tensile strength, and water absorption. Compressive strength measures the concrete's ability to withstand load, split tensile strength reveals its resistance to cracking under tension, and the water absorption test determines how much water the concrete can soak up, an important factor in its long-term durability.
A promising solution for making concrete more sustainable is the incorporation of recycled cellulosic pulp , obtained from used textiles and cellulose-based products . When processed into fibres , this material can reinforce concrete, enhancing tensile strength and crack resistance . Not only does this improvement make concrete more durable, but it also addresses the issue of waste management , promoting a circular economy by repurposing discarded materials. To fully harness the benefits of recycled cellulosic pulp, comprehensive analysis is necessary. This includes characterizing fibre properties such as length, diameter, and tensile strength to understand their influence on concrete’s performance. Optimizing the mix design is crucial to ensure an ideal balance between strength and workability. Mechanical testing , including evaluations of compressive, tensile strength, helps determine the overall impact of fibre reinforcement. Additionally, assessing durability in different environmental conditions ensures long-term reliability, while conducting an environmental impact analysis highlights the advantages of waste reduction and resource conservation.
The findings indicate that a moderate incorporation of recycled pulp can improve split tensile strength, leading to a more resilient concrete. However, excessive pulp tends to increase porosity, thereby reducing compressive strength. These results highlight the importance of optimizing the recycled pulp content to balance strength and durability, paving the way toward more sustainable concrete practices.

Integrating recycled cellulosic pulp into concrete presents an effective strategy for achieving greener and more sustainable construction practices. By reinforcing mechanical properties while simultaneously supporting eco-friendly development , this innovation plays a crucial role in building resilient infrastructure . As the construction industry continues to evolve, adopting innovative and sustainable materials will contribute to a more efficient and environmentally responsible future.
1. INTRODUCTION Concrete is an essential construction material, prized for its robustness, longevity, and adaptability. Made from a blend of cement, water, and aggregates, it plays a crucial role in the development of buildings, bridges, roads, and various infrastructure projects. However, with increasing emphasis on sustainability, enhancing its characteristics has become vital to secure its relevance in future construction efforts.
2. LITERETURE REWIEW P. Packialakshmi and R. Aasha Jyothi conducted an experimental investigation on concrete incorporating Ordinary Portland Cement (OPC) alongside hypo sludge. In their study, 10% of the OPC was consistently replaced with hypo sludge, while wood ash was introduced in varying proportions, ranging from 0% to 30%, as an additional cement substitute. The objective was to evaluate the
Enhancing concrete's durability results in longer-lasting structures that can resist weathering, chemical attacks, and abrasion, reducing maintenance costs over time. Strengthening concrete also allows for taller and more resilient structures , expanding the possibilities for architects and engineers. Additionally, developing eco-
