Abstract - This study investigates the flexural behavior of folded ferrocement panels reinforced with square welded and woven mesh. Ferrocement, recognized for its enhanced elasticity and durability, is ideal for roofing systems, particularly in affordable housing initiatives in developing economies. The experimental analysis focuses on how the number and type of wire mesh layers affect the ultimate flexural strength and load-deflection characteristics of these panels. The findings indicate that panels with increased mesh layers exhibit superior flexural strength and reduced deflection. Specifically, panels reinforced with square woven mesh showcase better performance in terms of load capacity and stiffness com-pared to those with square welded mesh. Furthermore, combining different mesh types optimizes the structural response, demonstrating the potential of ferrocement panels in modern construction practices. This research contributes to the understanding of effective reinforcement strategies for enhancing the performance of ferrocement structures. Key Words: Folded Ferrocement Deformation, Wire Mesh
Panels,
Refurbishment and strengthening of deteriorating civil infrastructures using such innovative materials ensure that older structures meet con-temporary safety and serviceability standards, making ferrocement a valuable material in modern civil engineering and construction. 1.1 Definition The definition by ACI Committee 549 was: "Ferrocement is a type of thin wall reinforced concrete construction, where usually hydraulic cement is reinforced with layers of continuous and relatively small diameter mesh. Mesh may be made of metallic materials or other suitable materials". In this definition, ferrocement is not confined to only steel wire mesh but other types of meshes as well. However, the definition ignores an important type of reinforcement currently in use in ferrocement, i.e. the combination of steel rods and wire mesh 1.2 Constituents of Ferrocement
Flexural
The constituents of ferrocement include the hydraulic cement mortar which should be designed according to the standard mix design procedures for mortar and concrete which includes Portland cement, water, sand, wire mesh and admixtures.
1. INTRODUCTION The industrialization of construction technology has emerged as a highly accepted and preferred method in modern building construction to minimize onsite construction. This can be achieved through various strategies, including the utilization of advanced cementbased composites for structural applications, such as ferrocement. Ferrocement, a form of rein-forced concrete made with closely spaced mesh or small diameter rods encapsulated in mortar, offers a robust solution to roofing and structural issues, particularly in developing economies with high demand for affordable housing. The material, first utilized by Pier Luigi Nervi in the 1940s, is known for its superior performance and versatility, providing greater elasticity and resistance to cracking. The use of prefabricated ferrocement components not only enhances construction efficiency but also significantly reduces time, safety concerns, environmental impact, and overall costs.
