Center 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...

Comparative Energy and Exergy Analysis for the Utilization of Alternative Fuels in the Cement Kiln

The cement industry is one of the most energy and carbon-intensive industries. The energy and carbon reduction is an important issue in this industry. The present work considers the use of alternative fuels in the cement kilns. The amounts of excess air, the location of fuel and air entrance, as well as the amount of produced gas stacks, are the main design and operational variables in the kiln...
