since reusing waste tire as a cheap filler is considerably high, in this study, recycled rubber to replace nr/br is used up to 15 phr and the positive and negative aspects of the rubber powder and reclaimed rubber in the physical, dynamical and processing properties are evaluated. the results showed that in the presence of recycled rubber, the cure rate, crack growth resistance, tear strength a...

Pyrolysis of polymeric wastes, including waste plastic bottles, discarded rubber tyres and pure water sachets, is one the environmental-friendly processes for valorization. However, continuous effort must be made to reduce cost implication pyrolysis process in terms time, money energy requirement. Based on this premise, study examined justification regarding heat absorption rate product yield, ...

Fox, A. J., Lindars, D. C., and Owen, R. (1974). British Journal of Industrial Medicine, 31, 140-151. A survey of occupational cancer in the rubber and cablemaking industries: results of five-year analysis, 1967-71. A mortality study of 40 867 subjects employed in the rubber and cablemaking industries on 1 February 1967 is reported. No evidence is found of a continued excess risk of neoplasms o...

Predicting tyre–road friction requires various inputs that are known with differing levels of confidence. This paper studies the prediction and associated experimental confirmation rubber on real roads at high sliding speeds. Friction predictions obtained from Persson’s flash temperature model: topography road surface is measured using an optical profilometer, while rubber’s viscoelastic modulu...

Recently, the use of recycled tyre polymer fiber derived from waste tires as a concrete reinforcement has received great deal attention. The is promising additive to for building materials which require resistance against cracking. In this work, effect treated and untreated on properties sand was studied. It shown that consists mainly different fractions crumb rubber, fiber, metal fiber. main c...

Petroleum-based plastics have many drawbacks: the large amount of energy required to produce the plastic, the waste generated as a result of plastic production, and the accumulation of waste due to slow degradation rate. It is because of these negative attributes of conventional plastic use that attention is being focused on environmentally friendly plastics from alternative sources. Albumin pr...

In this paper, we investigate the acoustic behaviour of building elements made of concrete doped with waste-tire rubber. Three different mixtures were created, with 0%, 10%, and 20% rubber in their composition. Bricks, lattice joists, and hollow blocks were manufactured with each mixture, and three different cells were built and tested against aerial and impact noise. The values of the global a...

When considering rubber tyre manufacturing from an occupational health viewpoint, three areas may be identified in which exposure to respirable materials are potentially harmful: the processing, curing, and talc areas. A study of the ventilatory function of the entire work force employed in the processing area in a rubber tyre manufacturing plant was undertaken to determine whether an acute red...
