What is Crumb Rubber Concrete(CRC) ?

Waste rubber is being used in several applications of Civil Engineering. One such application is in concrete replacing some part of fine aggregates with fine granules of rubber (scrap rubber from tyres). This concrete is called crumb rubber concrete(CRC) because of its usage of crumb rubber i.e the fine granules of grinded scrap rubber tyres.

when compared to traditional concrete, this concrete has got high ductility, energy dissipation and damping ratio. But, CRC has got low compressive strength when compared to conventional concrete. This concrete is an environment- friendly material since it is using waste rubber in place of natural resource i.e aggregates.
