摘要: Abstract This work presents a study on the potential use of waste crumb tire rubber and polyethylene terephthalate (PET) particles to produce sustainable concrete. In order find out feasibility such concrete in acidic environment, broad laboratory investigations terms crushing load, mass, ultrasonic wave velocity rubberized (TRC) PET (TRPC) were conducted assessed by Taguchi method. Afterwards, results compared with normal (NC) (NPC). 5, 10, 15 percent along substituted for fine natural aggregate aim reducing consumption virgin resources disposing wastes safe, effective, environmentally friendly approach. The significance levels experimental parameters, which indicate how factors affect velocity, determined using Analysis variance (ANOVA) statistical analytical showed that both NPC TRPC caused resistance against sulfuric acid increase after 60-day exposure. Although TRC comparison NC had lower acid, substituting significantly reached containing 10 PET. conclusion is can be employed case compensate downside environments and, so doing, large amount material disposed way.
