摘要：

Crumb rubber (CR) has long been utilized to enhance the stiffness of typically normal concrete (NC). Today, it is an eco-friendly material that is used in concrete. As failure because of fatigue and impact loadings is a concern in NC, the flexibility of CR aggregates might be the important key to solve this issue. Even if the mechanical properties of crumb rubber concrete (CRC) are marginally reduced, this may be addressed by treating the CR aggregates properly. CRC is made by substituting CR particles for a portion of the usual coarse and/or fine aggregates. It is currently being investigated to increase the durability and performance of concrete in tropical conditions under chloride attacks. In this study, in order to remove the environmental pollutants, CR aggregates are added to the NC samples with the ratios of 0%, 5%, 10%, and 15% and in the following, the behaviour of CRC samples are assessed and compared. Then, micro- silica with the ratios of 0%, and 7.5% is added to the mixing design of concrete samples and in the following, the effect of magnetic water is investigated, too. Also, CRC samples are treated in 10% H2SO4 solution for 2 h in order to evaluate the influence of acidic conditions. Next, the experimental procedure such as compressive strength test, Rapid Chloride Migration Test (RCMT), Rapid Chloride Permeability Test (RCPT) is performed to assess the mechanical and durability properties of CRC. The results of this study indicated that the CRC sample containing magnetic water, acidic CR and micro-silica had the greatest effect on the durability and mechanical properties. © 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
