This study is the study of feasibility of the use of the bamboo as reinforcement. Here bamboo was used as a reinforcing material. Recently global warming is the major issue on which we want to focus. Concrete is the most consumed material, with three tones per year used for every person in the world. Concrete has excellent characteristic in compressive strength, but in low in tensile strength. Steel commonly used in reinforcing material because of high tensile strength. The usage of steel as reinforcing, material is limited because it is costly and also has an effect on an air pollution during its manufacturing process. As an alternative to overcome this problem, bamboo material has used as a replacement of material, cheap and also available material. By replacing thiswe can achieve our main objective that cost effective construction and we also encourage the use of natural products by achieve we reduce the pollution impact on nature.

In this world of constantly increasing population and depleting resources there is urge to adopt cost effective and eco-friendly structures. This paper discusses the potential of bamboo and project the possibilities of usage of bamboo in the construction field. Bamboo is an ancient solution for the present-day problem. Bamboo is an appropriate substitute for the present convention building material such as steel and wood. The main characteristic of the bamboo which makes it a suitable building material is its high tensile strength which is equivalent to mild steel at the yield point and very good weight strength ratio making it high resilient against the forces created by the earth quakes and hurricanes. Bamboo can replace 70% of steel and wood used in the construction and reduce the cost by 40%. Bamboo can be used from scaffolding to every stage of construction like in footings, beams, columns, slabs, stair cases, etc. Bamboo is the renewable resource with amazing growth rate, rejuvenates the soil and grows in varied climatic conditions. Bamboo absorbs carbon dioxide and releases 35% more oxygen into the atmosphere than other hardwood trees.

There are few building codes also available for the usage of bamboo in the construction such as ISO 22156:2004 Bamboo structural design, ISO 22157:2004 Bamboo physical and mechanical properties, IS 9096:1979 Code of practice for preservation of bamboo for structural purposes, IS 15912:2018 Structural design using Bamboo. Thus, bamboo is environmentally friendly, Energy efficient and cost-effective material.
