Experimental Study of Crumb Rubber in Concrete
Crumb rubber is a material produced by shredding and commutating used tires. Waste tire dumping, disposal of these materials or burning these tires cause serious health and environmental problems. On the other side the traffic intensity also increasing day by day and thus bearing capacities also increased the long term goal of the work is to find a means to dispose of the crumb rubber in concre...
متن کاملInfluence of Rubber Size on Properties of Crumb Rubber Mortars
Studies on the properties and applications of rubber cement-based materials are well documented. The sizes of rubbers used in these materials varied. However, information about the effects of rubber size on the properties of rubber cement-based materials, especially pore structure, mechanical strengths, and drying shrinkage properties, remains limited. Three groups of rubber with major particle...
متن کاملAn overview of crumb rubber modified asphalt
Roadways are considered one of the most important elements of infrastructure and they play an essential role in our daily lives. In road pavement construction, the use of crumb rubber in the modification of bitumen binder is considered as a smart solution for sustainable development by reusing waste materials. It is believed that crumb rubber modifier (CRM) could be one of the alternative polym...
متن کاملInfluence of the Tunnel Shape on Shotcrete Lining Stresses
Tunnel excavation is frequently carried out in rock masses by the drill and blast method and the final shape of the tunnel boundary can be irregular due to overbreaks. In order to investigate the effects of overbreaks a study of the effect of tunnel boundary irregularity has been carried out. This is done developing a computational tool able to take into account fuzzy variables (i.e., thickness...
متن کاملZinc leaching from tire crumb rubber.
Because tires contain approximately 1-2% zinc by weight, zinc leaching is an environmental concern associated with civil engineering applications of tire crumb rubber. An assessment of zinc leaching data from 14 studies in the published literature indicates that increasing zinc leaching is associated with lower pH and longer leaching times, but the data display a wide range of zinc concentratio...
