Abstract
Recycling rubber in the building materials industry has several economic and environmental benefits because of its suitable for such high resistance to impact, light weight compared to other materials and acoustic and thermal insulation. The re-use of such rubber instead of burning has best impact to keep the environment.
Studies have shown that the use of rubber material in the concrete industry has a negative impact on the resistance to compression, bending and tensile strength as well as textures. Those properties could be improved through the use of chemical and mineral admixtures, and in this research was to use a self-compacting concrete for this purpose.
Self-compacting concrete (SCC), although developed with the aim to make easier compaction, is a new type of concrete that attains higher compressive strength and durability in comparison with ordinary concrete.
In this study, self-compacting rubberized concrete (SCRC) was investigated using Taguchi method and the design of experiment was performed using Minitab v.16 program. 16 mixes were carried out with four control factors. These factors are (Fine rubber, coarse rubber, fly ash and viscocrete ). Increase rubber content let to increase impact resistance, using the high percentage of both fine and coarse rubber (20%) increased the impact resistance by (453%) compared to mix with (0% rubber). Also increase viscocrete helps in enhancing the deterioration in the workability. In addition to analysis, Taguchi method was also used to predict the fresh and mechanical properties of SCRC. The analysis shows that the proposed Taguchi technique was adequate to predict the above properties. SCRC could be used in some applications as nonstructural element, which need low strength, more impact resistance and energy absorption such as crash barrier, road constructions and machines bases.
