Engineering is the application of technology for the benefit of society, and it encompasses various fields based on specific areas of application. Civil engineering, in particular, plays a crucial role in the construction and maintenance of infrastructure such as roads, bridges, dams, canals, and buildings. This project focuses on the utilization of civil engineering principles for the "Application of Ferrocement Technique to the Rural Sanitary Block System." The escalating costs of basic building materials like steel, sand, cement, brick, timber, and labor have led to a continuous rise in construction expenses. Conventional building materials and construction techniques are becoming less economical, especially for low and middle-income groups. Therefore, there is an urgent need to explore cost-effective construction techniques, either by upgrading conventional methods or by introducing innovative approaches. Ferrocement panels, the key focus of this project, offer a practical solution. These panels are easy to cast, cure, and manually erect on-site. The roofing system developed through ferrocement technology provides strength and rigidity, making it a cost-effective alternative. This makes it particularly well-suited for prefabricated construction, especially beneficial for people residing in rural areas. In essence, this project aims to leverage civil engineering principles to address the economic challenges associated with construction. By introducing ferrocement techniques, it seeks to provide a viable and cost-effective solution that can benefit not only low-income populations but also middle-income groups, contributing to sustainable and affordable construction practices in the realm of rural sanitation.
