A Review on Construction Technologies that Enables Environmental Protection: Rubberized Concrete

Abstract

Throughout the world, the disposal of used tires is a major environmental problem causing environmental hazards such as breeding ground for mosquitoes, producing uncontrolled fire and they are contaminating the soil and vegetation. Therefore, there is an urgent need to identify alternative outlets for these tyres, with the emphasis on recycling the waste tyre. Concrete is an excellent structural material and considered as essential for the modern civilization and human society. Now, the use of waste tires in concrete has become technically feasible and the concrete is being considered as light weight concrete. This study reviews the feasibility of using waste tires in the form of chips and fibers with different sizes in concrete to improve the strength as well as protecting the environment. Also it reviews the potential application in the field by exploiting its unique characteristics and properties. In this study, we outline the use of rubberized concrete in structural and non-structural members and show how it is suitable for the concrete, its uses, barriers and benefits and way to future study.

Analysis of the Transport Properties of Tyre Fiber Modified Concrete

“…Partially replacing the coarse aggregate of the concrete with some quantity of waste tyre cubes could give qualities such as low unit weight, high resistance to abrasion, absorption to shocks and vibrations, high ductility and brittleness to the concrete. Moreover the inclusion of rubber into concrete results in higher resilience, durability and elasticity (Lee et al, 1993;Eldin and Senouci, 1993a;Toutanji, 1996;Raghavan et al, 1998;Li et al, 1998;Bignozzi et al, 2000;Raghavan, 2000;Senthilkumaran et al, 2008). The literature reveals that the tests conducted by Eldin and Senouci (1993b) on concrete with tire chips and crumb rubber of sizes 19, 25 and 38mm considerably reduces the compressive strength and split tensile strengths but can withstand to absorb large amount of plastic energy.…”

“…The tests were conducted on composites formed with tyre fibers with lengths 25mm, 50mm, 75mm and different diameter of holes 4mm, 5mm and 6mm designated as L25-D4, L25-D5, L25-D6; L50-D4, L50-D5, L50-D6; and L75-D4, L75-D5, L75-D6. These tyre fibers were used to partially replace 0, 5, 10, 15, 20 and 25% of the coarse aggregate by total weight to cast different composites with varying % of tyre fiber mixes as proposed by Senthilkumaran et al (2008). The water and acid absorption were measured at the age 28days of all concretes.…”

The impact resistance effect of partially replacing coarse aggregate with ground-rubber aggregate in concrete

“…The stress concentration in the rubber fibre modified concrete is smaller than that in the rubber chip modified concrete. This means that the rubber fibre modified concrete can bear a higher load than the rubber chip modified concrete before the concrete matrix breaks [19] This study investigates the impact resistance effect of replacing coarse aggregate with ground-rubber aggregate and its t effect on density and toughness.…”

Environmental Concern in Managing Halal Food Supply Chain

“…Today global and local environmental problems face companies a new challenging issue which is known as natural environment (Ismail, 2010;Kumaran et al, 2008). Beamon (1999) believed that sourcing, manufacturing and logistics companies are the main cause of these problems.…”
