    Use of Scrapped Rubber Tires for Sustainable Construction of Manhole Covers

    Sadaqat Ullah Khan1, Afzal Ahmed1,*, Sajjad Ali2, Ayesha Ayub2, Ahmed Shuja1, Muhammad Ahsan Shahid1

    Journal of Renewable Materials, Vol.9, No.5, pp. 1013-1029, 2021, DOI:10.32604/jrm.2021.014344

    Abstract Scrapped tires from vehicles are produced in large quantities. Despite numerous existing uses of scrapped tires, a large quantity ends up at the landfill sites, which contributes to environmental degradation. The development of more applications of scrapped tire usage can reduce the disposal of tires at landfill sites. This research proposes a novel use of scrapped tires by using the strips taken from scrapped tires in replacement of steel bars as reinforcement. Manhole covers were produced using scrapped tires by completely replacing the steel with scrapped tires. Four different samples of manhole covers were prepared and tested. The highest bearing… More >

    Experimental Study of Waste Tire Rubber, Wood-Plastic Particles and Shale Ceramsite on the Performance of Self-Compacting Concrete

    Lei Tian, Liuchao Qiu*, Jingjun Li, Yongsen Yang

    Journal of Renewable Materials, Vol.8, No.2, pp. 154-170, 2020, DOI:10.32604/jrm.2020.08701

    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… More >
