Performance Evaluation of Recycled Mask as Permanent Formwork in Reinforced Beams

The construction industry heavily relies on traditional formwork materials such as timber, steel, plywood, and aluminum, which contribute to environmental degradation, resource depletion, and high costs, necessitating the exploration of sustainable alternatives. This study explores the innovative use of single-use masks as a sustainable and environmentally friendly alternative to these traditional formwork materials. This research evaluates the feasibility of formwork as a permanent member of a structure through Finite element analysis. The analysis was performed using Fusion 360, where stress-strain and stress-displacement behavior were inspected under different loads. The Finite element shows negligible displacement and strain, substantiating structural integrity in the suggested formwork. In addition, the simulations verified that the reinforced beam maintained its performance inside bearable limits. The strain values obtained were 0.00001-0.00009 as the load increased, which lies in the elastic strain limit. The effect of pressure of concrete exerted on the walls of formwork examines stress-strain behavior to assess structural performance. The study also discusses the physical and mechanical properties of the proposed formwork system and compares it with conventional alternatives across various construction applications. This study evaluates the different formworks of various construction processes, enhancing construction practices to be more cost-coherent, sustainable, and environmentally strategic.
