Abstract
Ferrocrete is a versatile construction material & highly suitable for a variety of structures. Ferrocrete is a composite material made up of cement, sand, skeletal steel, wire mesh and water & has unique combination of high strength and stiffness. As per ACI committee 549 Ferrocrete is a type of thin reinforced concrete construction where usually hydraulic cement is reinforced with layers of continuous and relatively small dia. It is noticed that if in the circular column weak concrete or lean concrete of grade say M10 or M15 if placed and if the same is surrounded by mortar of higher strength the overall strength of concrete is far more than the lean concrete placed inside. The project undertaken consists of placing lean concrete of M10 strength in a cylindrical confinement of 8 cm Φ and the same will be surrounded by mortar with outside diameter of 15 cm with 30cm height. With providing 1 wire mesh with 1 chicken mesh or 2 wire mesh with 2 chicken mesh as confinement. On carrying out compressive strength and Splitting Tensile strength test of the mould on U. T. M. Increase in the strength of the concrete due to lateral confinement is determined.
