Abstract

Waste tyre rubber is one of waste material, which is produced excessively worldwide every
year. The disposal of this rubber has a major problem in the environment as its decomposition takes a long
time and also produces environmental pollution. One of the alternative solutions is to use the scrap waste tyre
rubber as a partial replacement of natural aggregate in concrete. This paper presents the experimental study
on the effect of waste tyre rubber in the form of crumb rubber as a partial fine aggregate replacement on
normal and fly ash concrete. The content of fly ash in the fly ash concrete was 15 % by replacing the cement
weight. A total of 60 concrete cylinders were cast and tested to evaluate its compressive and splitting tensile
strength. The use of crumb rubber from the waste tyre in both normal concrete and FA concrete is 5%, 10%,
15%, and 20% based on fine aggregate volume. The results show that rubberized concrete has low
workability, compressive and tensile strengths but has greater crack resistance when compared with ordinary
concrete. The more percentage of crumb rubber on both the rubberized normal concrete (RNC) and the
rubberized fly ash concrete (RFAC) result in a higher decrease in compressive and tensile strengths of the
concrete. Compared to RNC, RFAC has a higher strength in each crumb rubber content due to the presence
of fly ash. From this study, it is recommended to use the crumb rubber as a fine aggregate replacement with
the maximum content of 10% and 15% on normal concrete and fly ash concrete, respectively.
