Abstract
In recent decades, the utilization of waste tires, plastic and artificial shale ceramsite as alternative fine aggregate to make self-compacting concrete (SCC) has been recognized as an eco-friendly and sustainable method to manufacture renewable construction materials. In this study, three kinds of recycled aggregates: recycled tire rubber particles, wood-plastic particles, artificial shale ceramsite were used to replace the sand by different volume (5%, 10%, 20% and 30%), and their effects on the fresh and hardened properties of SCC were investigated. The slump flow and V-funnel tests were conducted to evaluate the fresh properties of modified-SCC mixtures. The hardened properties include 3, 7 and 28-day compressive strengths, axial compressive strength, static elastic modulus, and compressive stress-strain behavior at 28 days. The test results showed that the incorporation of these three kinds of alternative aggregates had a negative impact on the fresh properties of SCC. Besides, the 28-day compressive strength and axial compressive strength decreased with the increase of rubber and wood-plastic particles content. In this experiment, all the three kinds of recycled aggregates can improve the ductility and deformability of SCC, and the most excellent performance comes from SCC with recycled rubber particles.
