Proposal for Alternative Recycled Plastic Formwork System for Tie Columns and Tie Beams

Abstract:

This study proposes an alternative formwork system using recycled plastic to reduce the use of wood in the construction of tie columns and tie beams in San Pedro Sula, Honduras. The main objective is to develop a more sustainable and efficient solution to reduce wood consumption and the high costs that these formworks represent in projects. A geometric design was developed using reinforced recycled plastic boards, tailored to meet the structural needs of secondary concrete elements. The study applied a comparative methodology, evaluating the proposed system against traditional wooden formwork based on parameters such as assembly time, reuse potential, resistance, and material reduction. Results showed a 20% to 30% decrease in formwork assembly and disassembly time, along with an over 80% reduction in wood consumption. The recycled plastic formwork demonstrated greater durability and resistance to moisture compared to wood, offering improved performance in terms of lifespan and reusability. In conclusion, the proposed system proved to be a functional, cost-effective, and environmentally friendly alternative for the construction sector in Honduras. It also promotes the reuse of plastic waste in the development of modern, sustainable construction technologies.
