Tensile Strength and Toughness Index of Flyash-lime –gypsum Mixed with Dry/Treated Tire Chips

With the alarming growth in vehicle population in world, scrap tires are beginning to pile up. The paper presents an engineering overview of use of shredded scrap tires chips with fly ash, lime and gypsum mix. It has been observed that the tensile load, diametral strain and toughness characteristics of the reference mix mixed with dry tire chips can be increased by providing surface treatment of tire chips with carbon tetra chloride, sodium hydroxide and water. Beside this, it has been observed that curing methods and curing periods has also prominent effect on the tensile and toughness characteristics of reference mix mixed with dry/treated tire chips. As the composite formed by mixing fly ash, lime and gypsum with treated tire chips has shown increased toughness characteristics, hence the composite material find new application in those construction where there is more requirement of toughness characteristics. Utilizing some portion of these wastes like fly ash and tire chips in this way will reduce the quantity of the waste-requiring disposal. Moreover, the disposal in this way will be in an environmental friendly manner.
