Properties of concrete containing scrap-tire rubber--an overview.
Solid waste management is one of the major environmental concerns in the United States. Over 5 billion tons of non-hazardous solid waste materials are generated in USA each year. Of these, more than 270 million scrap-tires (approximately 3.6 million tons) are generated each year. In addition to this, about 300 million scrap-tires have been stockpiled. Several studies have been carried out to re...
متن کاملCenter for By-Products Utilization PROPERTIES OF CONCRETE CONTAINING SCRAP TIRE RUBBER – AN OVERVIEW
Solid waste management is one of the major environmental concern in the United States. Over 5 billion tons of non-hazardous solid waste materials are generated in US each year. Out of which more than 273 million scrap tires (approximately 3.6 million tons) are generated each year. In addition to this, about 3 billion tires are stockpiled. Several studies have been carried out to reuse scrap tir...
متن کاملEngineering Controlled Low Strength Materials Using Scrap Tire Rubber
An investigation was conducted to determine the influence of recycled scrap tire rubber on the engineering properties of controlled low strength material (CLSM). With control over the ultimate compressive strength of CLSMs being key for applications such as backfilling utility trenches where re-excavation is often necessary, incorporation of scrap tire rubber into the CLSM mixture is a viable w...
متن کاملMicrobiological deterioration of vulcanized rubber.
Data are presented which show that the constitution of the recovery medium exerts an appreciable effect on the apparent thermal resistance of spores of Putrefactive Anaerobe 3679. The routine use of a simple yeast extract-starch medium (YES) as a recovery medium in thermal resistance studies on this organism is recommended. In addition to giving thermal resistance values comparable to those obt...
متن کاملVulcanized rubber foot for lower limb amputees.
A prosthetic workshop was started some years ago at the S.M.S. Medical College Hospital , Jaipur , t o meet the growing demands of the local populat ion. Unlike the premier limb-fitting centres in India which still cater for the more affluent sections of society, it was decided that this centre would also look after the p o o r rural amputees . I t soon became apparent that a disturbing number ...
