Investigation of mechanical and durability properties of recycled aggregate concrete containing crumb rubber considering a new model of elastic modulus
Natural gravel and Sand are growing more and more expensive due to its scarcity. Therefore, replacing natural aggregates with recycled materials has been a concern of researchers. In this paper, crumb rubber was utilized to supersede a few of the aggregate in percentages of 5, 10, and 15 aggregate volume. In concrete containing 15% rubber crumbs, 10%silica fume, and 10%zeolite were used along with crumb rubber. The findings of this investigation indicated that concrete containing 15% crumb rubber causes the greatest decline in compressive strength. Comparative to control concrete, compressive strength was decreased by 35% at 28 days and 36% at 7 days by substituting 15% of crumb rubber with aggregate volume. Additionally, it was discovered that the compressive strength of concrete containing 15% rubber crumbs rised by 23% and 33% at 28 days, and 21% and 34% at 7 days, respectively, when the mixture was containing 10% zeolite and 10% silica fume. Also, the greatest recline in flexural strength, tensile strength, and modulus of elasticity was related to concrete containing 15% crumb rubber, which was improved by adding 10% pozzolan. Finally, an elastic modulus prediction model for this type of concrete (recycled aggregate concrete) is presented.
