“…Comparable trends in the results obtained by researchers (Li et al 2004a, Li et al 2004b, Garrick 2005 where yarns from waste tires were used; however the type and dimensions of yarns used in the said tests were different from the yarns used in our tests. The tire cord yarn can be used like addition for concrete.…”

“…The most similar tests were done in the US (Li et al 2004a, Li et al 2004b, Garrick 2005 where yarns from waste tires were used; however the type and dimensions of yarns used in the said tests were different from the yarns used in our tests. In these tests (Li et al 2004a, Li et al 2004b, Garrick 2005 tires were cut into trips by hand. It was determined, that compressive strength of the rubberized concrete decreases because of the weak bond between the waste tire and concrete matrix.…”

“…The concrete without waste tire failed a lot sooner than the rubberized concrete, concrete with rubber is much tougher than concrete without rubber. These researchers ( (Li et al 2004a, Li et al 2004b, Garrick 2005) done conclusion, that waste tire modified concrete can be used in industrial floorings such as factory and warehouse floors where the increased impact resistance and post-cracking ductility will be beneficial.…”

Abstract. Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation. Chemical analyses revealed significant decreases in TNT concentrations, including reduction of some of the TNT to its amino derivates during the 28-day tests. The combination of bioaugmentation-biostimulation approach coupled with rye cultivation had the most profound effect on TNT degradation. Although plants enhanced the total microbial community abundance, blue fenugreek cultivation did not significantly affect the TNT degradation rate. The results from molecular analyses suggested the survival and elevation of the introduced bacterial strains throughout the experiment. Keywords: TNT, bioaugmentation, biostimulation, phytoremediation, microbial community.

“…In addition to this, more than seven million tires are currently stockpiled in Rhayyah northern of Kuwait (Rubber Manufacturers Association, 2000). These stockpiles are dangerous not only due to potential environmental threat, but also from fire hazards and provide breeding grounds for rats, mice, vermines and mosquitoes (Khatib and Bayomy, 1999;Guneyisi et al, 2004Eldin and Senouci, 1993, 1994Toutanji, 1996;Fedroff et al, 1996;Topcu, 1995 Li et al, 2004).

“…Their paper contains limitations and concerns of using tire-rubber concrete as well. Li et al (2004) used waste tires in the form of fibers and developed waste tire fiber modified concrete. The static and dynamic behavior of recycled tire-rubber-filled concrete was investigated by Hernandez-Olivares et al (2002 In this paper, tire-rubber concrete properties are investigated using mechanical and non-destructive testing for different sizes of tire particles.…”

Solid waste management is one of the major environmental concerns all over the world and in Kuwait. Over 5 billion tons of non-hazardous solid waste materials are generated in Kuwait each year. Of these, more than 2 million scrap-tires (approximately 2 million tons) are generated each year. In addition to this, about seven million scrap-tires have been stockpiled. Due to the increasingly serious environmental problems presented by waste tires, the feasibility of using elastic and flexible tire-rubber particles as aggregate in concrete is investigated in this study. Tire-rubber particles composed of tire chips, crumb rubber, and a combination of tire chips and crumb rubber, were used to replace mineral aggregates in concrete. These particles were used to replace 10%, 15%, 20%, and 25% of the total mineral aggregate's volume in concrete. Cylindrical shape concrete specimens 15 cm in diameter and 30 cm in height were fabricated and cured. The fresh rubberized concrete exhibited lower unit weight and acceptable workability compared to plain concrete. The results of a uniaxial compressive strain control test conducted on hardened concrete specimens indicate large reductions in the strength and tangential modulus of elasticity. A significant decrease in the brittle behavior of concrete with increasing rubber content is also demonstrated using nonlinearity indices. The maximum toughness index, indicating the post failure strength of concrete, occurs in concretes with 25% rubber content. Unlike plain concrete, the failure state in rubberized concrete occurs gently and uniformly, and does not cause any separation in the specimen. Crack width and its propagation velocity in rubberized concrete are lower than those of plain concrete. Ultrasonic analysis reveals large reductions in the ultrasonic modulus and high sound absorption for tire-rubber concrete.
