Structural behaviour of ferrocement channels slabs for low cost housing

Öz:
This paper presents a new pre cast U-shape ferrocement forms reinforced with various types of metallic and non-metallic mesh reinforcement. This research was designed to investigate the feasibility and effectiveness of employing various types ofreinforcing meshes in the construction of structural slabs incorporating permanentU-shape ferrocement forms as a viable alternative for conventional reinforced concrete slabs. Fiber glass meshes reinforcement was used for durability and protectionagainst corrosion of reinforcing steel. To accomplish this objective, an experimentalprogram was conducted. The experimental program comprised casting and testingten slabs having the total dimensions of 500x100x2500 mm incorporating 40 mmthick U-shape permanent ferrocement forms. Series A consists of two conventionallyreinforced concrete slabs were cast and tested and used as control slab without fibersand with fibers, volume fraction, 2.05 % and 2.177 %. Series B comprises of two slabsreinforced with one and two layers of expanded steel mesh, volume fraction 2.09 and2.42% respectively. Series C comprises two slabs reinforced with two and four layersof welded galvanized steel mesh, having volume fraction 2.05 and 2.189% respectively. Series D Consists of two slabs reinforced with one layer and two layers of fiberglass meshes, having volume fraction 2.107 and 2.277% respectively. Series E comprises two slabs reinforced with 2 layers expanded steel mesh and one layer expanded steel mesh, having volume fraction 1.357 and 2.750 % respectively. The testspecimens were tested as simple slabs under four-line loadings condition on a spanof 2300mm. The performance of the test slabs in terms of strength, stiffness, strains,cracking behavior, ductility, and energy absorption properties was investigated. Thebehavior of the developed slabs was compared to that of the control slabs. The experimental results showed that high ultimate and serviceability loads, better crackresistance control, high ductility, and good energy absorption properties could beachieved by using the proposed slabs and low cost compared with control specimen.
