Effect of Recycled Rubber Particles on the Deicing Salt-Scaling Durability of Concrete
The present study investigated the effect of reused rubber particles (RRP) on the deicer salt durability of ordinary concrete. Four mixtures were designed, a control concrete (CC) and three other rubber concretes obtained by partial substitution of natural dune sand aggregate with reused rubber particles with 0%, 3%, 6%, and 9% w/w. All studied concretes were subjected to the combined effect of freeze/thaw (56 and 120) cycles with the deicer salt solution of 3% NaCl. The results indicated that RRP improved the deicer-salt scaling resistance of rubber concrete strongly compared with the control. The observed innovative property of RRP could be applied to cement-based materials to improve their deicer salt durability. Further, this environmentally friendly practice could reduce the stock of waste tires and offer a renewable source of construction aggregates.
