“…Due to the large amount of ground needed and the threat to the environment caused, burying is not effective for the disposal of waste tires. The reuse of tire rubber as an additive to or replacement of construction materials has become a highly preferable option for energy saving and environmental protection [1,2].…”

Experimental Investigation on the Freeze–Thaw Resistance of Steel Fibers Reinforced Rubber Concrete

The reuse of rubber in concrete results in two major opposing effects: an enhancement in durability and a reduction in mechanical strength. In order to strengthen the mechanical properties of rubber concrete, steel fibers were added in this research. The compressive strength, the four-point bending strength, the mass loss rate, and the relative dynamic elastic modulus of steel fiber reinforced rubber concrete, subjected to cyclic freezing and thawing, were tested. The effects of the content of steel fibers on the freeze–thaw resistance are discussed. The microstructure damage was captured and analyzed by Industrial Computed Tomography (ICT) scanning. Results show that the addition of 2.0% steel fibers can increase the compressive strength of rubber concrete by 26.6% if there is no freeze–thaw effect, but the strengthening effect disappears when subjected to cyclic freeze–thaw. The enhancement of steel fibers on the four-point bending strength is effective under cyclic freeze–thaw. The effect of steel fibers is positive on the mass loss rate but negative on the relative dynamic elastic modulus.

“…Balunaini et al [2] reported that rubber waste can be used in several civil engineering applications such as embankment fill material, drainage material, vibration dampening material underneath railways, thermal insulation layer and asphalt rubber paving layer. In addition, rubber wastes were used as fine and coarse aggregates in concrete material as reported in several investigations [7,9,13,18,21].…”

In this study, an alternative and environmentally friendly method for the reinforcement of dune sand is proposed. This technique consists of using randomly distributed rubber fibers to improve the engineering properties of sand. Rubber fibers are added to the sand with different percentages: 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75 and 2% of dry weight of sand. The experimental program carried out consists of investigating the effect of rubber fibers on the shear strength properties of sand. Reinforced and unreinforced samples are tested in the dense as well as loose state. The results obtained showed that the inclusion of rubber fibers in dune sand will improve the engineering properties of various civil engineering applications such as shallow foundations and slope. Therefore, incorporation of rubber fibers can enhance the shear strength characteristics, peak and residual strengths, and introduce more ductility to the mechanical behavior of sand. In addition to the technical effect, this paper emphasizes another environmentally attractive option, which is the use of rubber fibers as reinforcements for granular soils as this helps to remove some parts of these wastes and protect the environment.

“…The advantage of cryogenic grinding over other ways of grinding rubber is its lower cost (Sunthonpagasit and Duffey, 2004;NSTDA, 2013). Crumb rubber could only be used in applications that do not require vulcanisation such as in recycled crumb rubber modifier asphalt pavement, Portland cement concrete, roller compacted concrete pavement athletic surfaces and fields, automotive parts and tyres, kid's playgrounds, and other safety surfaces (Serumgard, 1998;Siddique and Naik, 2004;Cao, 2007;Meddah, Beddar and Bali, 2014;Thomas and Gupta, 2015).…”

“…The reclaimed rubber can be used in many products, including tyres, pedestrian concrete areas, animal mats used in stables and insulation tiles used in metro railways for reducing noise level. There is a promising future for the use of discarded tyre rubber as a partial substitute for fine aggregates in concrete, which can result in huge environmental and sustainability benefits (Thomas and Gupta, 2015).…”

Abstract:This study aims to describe the current problems of the end-of-life tyre system, and propose possible end-of-life tyre management program for Thailand based on cost and environmental perspectives. This study can showcase the process for countries where end-of-life tyre management has not yet been implemented or countries that are facing problems with their end-oflife tyre management systems. Research findings indicate that, without an endof-life tyre program through which customers would be charged a treatment fee, it is not feasible for tyre collectors to collect the used tyres that are discarded more than 150 km from a recycling plant. To increase the end-of-life tyre treatment percentage, a treatment fee must be collected, and the free market system should be used. Subsidy settings, estimated at approximately 20 baht/new tyre or $0.6/new tyre for the collection, processing and use of scrap tyres, should be configured to ameliorate the overall process.Keywords: end-of-life tyre management; life-cycle costs of end-of-life tyre; used tyre management policy; used tyre recycling.Reference to this paper should be made as follows: Mangmeechai, A. (2017) 'Moving towards sustainable end-of-life tyre management from the cost and environmental perspectives: a case study of Thailand', Int.
