Abstract:

For concrete construction, one problem that a constructor often encounters is that there is a large amount of fraction of reinforcing steel caused by cutting. This study shows a method of reducing waste from the cutting. The reinforcing steel used in concrete is virtually 100% recycled from other metal products. More than 7 million tons of scrap steel is recycled into reinforcing bars every year, virtually the entire feedstock. This recycling avoids massive energy expenditure - one ton of steel reinforcing bars would otherwise require about 2,500 pounds of ore, 1,400 pounds of coal, and 120 pounds of limestone. The steel industry believes that sustainable development must meet the needs of the present without compromising the ability of future generations to meet their own needs. Within this, a green economy delivers prosperity for all nations, wealthy and poor alike, while preserving and enhancing the planet’s resources. The main objective of this study is to experimentally investigate the flexural behavior of RC beam containing coupler rebars and welded rebar and the experimental parameter is grade of concrete. Coupler and welding methods are used in this study to find which method will give more strength between both. Experimental results revealed that the coupler beam gives more strength than the welded beam but not more than the control beam specimen for 7 days and 14 days and 28 days. From the above observation it is suggested that we can use couplers in the rebar joining than the welding of rebar which gives better strength and also avoids congestion.
