“…At the higher replacing proportions (30%, 40% and 50% by volume), the slumps relatively increased. Our results are in good agreement with the slump test results reported by previous studies (Balaha et al, 2007;Azmi et al, 2008;Aiello and Leuzzi, 2010;Onuaguluchi and Panesar, 2014;Elchalakani, 2015) where the workability of fresh rubberized concrete increased with increasing rubber contents. For instances, Aiello and Leuzzi (2010) showed that the workability of rubberized concrete was slightly improved when coarse or fine aggregates were partially replaced with rubber shreds.…”

Article HistoryThis study aims to explore the possibility to use rubber particles derived from discarded tire as aggregates for replacing fine and coarse natural aggregates to produce cement concrete towards resource recovery and environmental protection in Vietnam. The experimental results showed that the workability of fresh rubberized concrete was improved when replacing natural fine aggregate (sand) with fine rubber particles (2.5-5 mm) at the replacing proportions of 30-50% by volume, and when replacing natural coarse aggregate (crushed stone) with coarse rubber particles (5-20 mm) at the replacing proportions of 10-30% by volume. With respect to the mechanical properties of hardened rubberized concrete, a larger reduction in the compressive and flexural strengths was generally found when the replacing proportions increased and when coarse aggregate rather than fine aggregate was replaced by rubber particles at all replacing proportions. However, the study results also indicated that using fine rubber particles for replacing fine natural aggregate at the low replacing proportion (up to 10%) might not cause the significant effect on the compressive and flexural strength of rubberized concrete.Contribution/Originality: This is the first ever study in Vietnam to investigate the potential for using rubber particles derived from discarded tires to replace natural aggregates in producing cement concrete towards resource recovery and environmental protection in Vietnam.

“…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.

“…To improve rubber-cement paste chemical/physical bonding [18], several rubber pre-treatments have been investigated such as washing with water [21,35,42], polyvinyl alcohol [43], NaOH [13,41,44,45], Ca(OH) 2 [46], silane coupling agents [47], organic sulphur compounds [48] or acid [40], as well as partial oxidation of the rubber surface [49], exposure to UV radiations [50] or pre-coating with cement [51], mortar [26], silica fume [39], limestone [52] or sand [45]. Despite some success in rubber pre-treatments (strength increase in the range of 3-40% [18,26,41,51,52]), results are often scattered and inconclusive, particularly when mixes with pre-treated rubber are not compared to mixes with as-received rubber [35,42]. The effects of the pre-treatments on the concrete hydration reaction and long term durability have not been investigated.…”
