Crumb Rubber Concrete Formation by Partial Replacement of Fine Aggregates

Abstract

AbstractConcrete is mostly used construction material in the construction of structures, bridges. It contains natural aggregates and cement. The use of aggregates includes fine and coarse aggregates in concrete which is likely to deplete natural resources and also creating environmental problems. There is a need to use alternative materials which can reduce the requirement of natural resources. Nowadays, huge amount of tyre is generated as waste which creates the disposal problem. It has become a major environmental issue. Several researchers have been done to use tyre waste as an alternate material. In this paper, crumb rubber is used as a replacement for natural fine aggregates in concrete at 0, 5, 10, 15 and 20%. The compressive strength of M30 grade concrete using crumb rubber as partial replacement of fine aggregate was investigated as per IS10262-2009. The compressive strength of crumb rubber concrete was obtained satisfactory when concrete mix was made 10% partial replacement of fine aggregate with crumb rubber. In many applications, crumb rubber concrete may be useful as compared to conventional concrete in spite of less compressive strength. Crumb concrete has many desirable properties which are useful many structural applications.KeywordsConcreteCrumb rubberCompressive strengthFine aggregateWaste material
