Use of Waste Tires as Transverse Reinforcement and External Confinement in Concrete Columns Subjected to Axial Loads

Approximately 246 million waste tires are generated annually in the United States. That is roughly three per four individuals country. Most end up landfills, adversely affecting environment. In last two decades, researchers have explored using tire chips concrete to replace a portion of coarse aggregates. Past studies indicated that 50% aggregates can be replaced with chips. This research proposes recycled rubber and columns. The used as external transverse reinforcement plain function formwork during pour while providing confinement after curing. concepts this for retrofitting structures inadequate foundations constructing new structures. After analyzing data from research, axial compressive test confined columns was greater on average than unconfined effectiveness ratio all specimens one.
