This research proposal investigates the utilization of paper waste fiber in mortar to promote sustainable construction practices. The study addresses the environmental impacts of traditional building materials, such as cement, and explores the potential of recycling paper waste to enhance mortar properties. The proposal includes a comprehensive literature review, outlining the current knowledge and research gaps in this field. It defines specific aims and objectives, detailing the methodologies to be employed, including material selection, sample preparation, and data collection methods. The experimental plan involves tests like compressive strength, flexural strength, and microstructure analysis to assess the performance of paper waste fiber-reinforced mortar. The research aims to reduce waste, minimize environmental impacts, and potentially lower construction costs. The findings are expected to contribute valuable insights into the development of eco-friendly building materials. This research emphasizes the importance of sustainable construction and the need to explore alternative materials.
