Prediction of self compacted rubberized concrete properties using Taguch methods

Özet

The effect and optimization of using self-compacting rubberized concrete was inves- tigated by using Taguchi method. Design of experiment was performed via orthogo- nal array to accommodate four factors with four levels. These factors were the per- centage of fine rubber, coarse rubber, fly ash and viscocrete in the concrete mix. The signal-to-noise (S/N) ratio and the analysis of variance (ANOVA) were employed to study the performance characteristics of self-compacting rubberized concrete (SCRC). Rubberized concrete can be improved using the concrete proportioned as self-compacting concrete. The results indicate that there was a reduction in the strength with increasing rubber content but there was an increase in impact re- sistance. However, the replacement of 10% of coarse aggregate with coarse rubber gave more strength than that of zero rubber mix by 124% at 90 days. Replacement of 20% of both fine and coarse aggregates with fine and coarse rubber respectively, in- creased impact resistance by 453% compared to the corresponding SCRC control mix.
