Abstract

EXPERIMENTAL INVESTIGATION ON UTILIZATION OF CRUMB RUBBER IN RIGID PAVEMENTS

N. Mounica*, Hari Krishna Karnam, V. John Prasanth

ABSTRACT

As the mode of transportation is increasing worldwide, there is an enormous increase in crumb rubber in landfills, which is a serious threat to the environment. In order to reduce the trash and mining of natural sand, which distresses the bridges, river banks and nearby structures, replacement of filler material is the best choice. In view of this aspect crumb rubber from landfills will be a good option for replacement in concrete. In this project an emphasis on replacement of natural material is given. Natural fine aggregate is replaced with crumb rubber at varying percentages i.e., 5, 10, 15, 20 and also adding fly ash to the cement at 5 percentage respectively, and adding 0.2% of silane coupling agent to the fly ash modified cement at all proportions. Related comparisons for the mechanical properties of crumb rubber modified concrete at different proportions in line with the conventional concrete were found out.
