Abstract – Now days, rural region of India is facing the
problem of drought as a reason of not storing rain water and lack of ground water. Weir can overcome this problem but weirs in RCC are not economical. Moreover due to lack of financial funds, it is not easily possible to construct weir in RCC. As a result, weir in ferrocement can be solution to overcome this problem, as it has capability to prevail over this cost barrier. The foremost goal of this study is to examine the parameters of non-gravity weir in ferrocement in terms of suitability, economic approach and construction period. The current work is the study of construction of non-gravity weir in ferrocement and study says that ferrocement can be good substitute to RCC in non-gravity weir construction as it will take less time and less cost to construct as compared with RCC. Key Words: Ferrocement, non-gravity weir, cost effective, time effective, RCC.
1. INTRODUCTION Ferrocement technology was invented by Joseph Louis who constructed a boat with the system in 1848. Ferrocement is the composite of iron (ferrous) and cement. It combines the properties of thin sections and high strength of steel. In construction of ferrocement structure wire meshes are filled in with cement mortar. It is a composite which is formed with closely knit wire mesh, tightly wound round skeletal steel and impregnated with rich cement mortar. As encasing material, ferrocement is resistant to take tension and flexure. It also takes over the properties like durability and imperviousness. Ferrocement structure are usually constructed with less thickness ultimately reduces the required cement mortar which eventually minimize the construction cost. In rural region in India where there is lack of financial funds ferrocement can be an effective and low-cost alternative construction material. The prominent goal of this research is to propose a non-gravity weir using ferrocement technology which will reduce cost and time of weir projects.

proposed ferrocement weir and RCC weir has done. Additionally comparative study is also given showing property comparison of ferrocement and RCC.
2.1 Suitability of Ferrocement for Weir Structure Initially ferrocement was used in the construction of boats as it is highly impermeable and light weight. A typical use of ferrocement comprises water tanks, silos, boats and roofing [5]. Ferrocement structures have upper hand over the typical materials like RCC and wood as these are strong, durable and waterproof [4]. Study says ferrocement has excellent tensile and flexural behavior also it is an optimum low-cost material for low-rise, earthquake resistant structures [3]. Ferro-cement has considerable strength and it can maintain functional water-tightness. Plain concrete has little resistance to impact (impulsive loads). The addition of finely dispersed steel increases the impact strength significantly. Although the mortar in tension cracks readily, the steel wires allow for a significant absorption of energy and act as crack arrestors [9]. By studying the properties of ferrocement, we concluded that ferrocement can be a good substitute to the RCC in weir construction.
2.2 Technical Parameters Under previous heading we end up with non-gravity weir can be constructed using ferrocement technology. We have designed a non-gravity weir in ferrocement for catchment area 336 m2. Study says, an arch i.e. semicircular shape is strong enough for resisting the compressive force of water on the upstream side of weir. A curve or arch is the strongest form of structure because lateral pressure on arch cause the walls of arch to go into partial compression rather than tension [10]. So we have devided the 8m vertical wall of weir in semicircular vaults with intermediate inclined counterforts to counter deflection. The inner diameter of vaults is 1.2m and outer diameter is 1.9m. the thickness of each vault is 35mm [fig.9]. ISO 9001:2008 Certified Journal
