Abstract
Ferrocement is widely used because of its excellent behavior pf ferrocement under flexural, and impact strength. Ferrocement also has excellent mechanical properties. In this study, total 16 ferrocement panels were modelled of M50 grade of concrete. The thickness of ferrocement panels considered is 15mm, 20mm and 25mm. Galvanized welded mesh is used as reinforcement in panels. This wire-meshes were layered in 2, 3, 4 and 5 layers. High velocity impact test is done by Ak-47 bullet striking with a velocity of 150, 250, 350, 450, 550, 650 and 750 m/s for each panel. All this panels were modelled in design modeler of Ansys explicit Dynamics. Deformation, Equivalent Stress and Normal Stress of all the panels are evaluated and compared by analyzing in ANSYS Explicit Dynamics. From the past researches and the conclusions made by these researches, we can see positive chance in the utilization of waste foundry sand in construction field. As these results gives the great emphasis towards the development on environment friendly and economical constructions.
Highlights
Ferrocement is constructed as a thin wall reinforced concrete made up with hydraulic cement mortar which is reinforced with closely spaced layers of continuous and tiny sized wire-mesh
Various Ferrocement models are made by varying parameters such as thickness, number of mesh layers and waste foundry sand
In high velocity impact loading by AK-47 bullet, The equivalent stress of 15mm thick panel is 30% more than 20mm thick panels using 2 layers of woven mesh for M30 grade of mortar while the equivalent stress of 20mm thick panel is 20% more than 25mm thick panels using 2 layers of woven mesh for M30 grade of mortar
Summary
Ferrocement is constructed as a thin wall reinforced concrete made up with hydraulic cement mortar which is reinforced with closely spaced layers of continuous and tiny sized wire-mesh. The materials used to make wire-mesh can be metals or different alloys. RCC has been the most used material in construction industry all over the world. Rates of materials used in RCC are increasing day by day. Availability of materials is one of the major issues construction industry is currently facing. Ferrocement can be perfect substitute for RCC in some structures which provides same or more strength at low price. Ferrocement consist of mortar reinforced by wire mesh to form component having comparatively small thickness, high sturdiness and resilience which results into high strength and rigidity. To analyze the response of ferrocement in unconventional applications and numerical simulations, the Revised Manuscript Received on June 15, 2020. * Correspondence Author
