The Influence of Treated and Untreated Crumb Rubber on Concrete Mechanical Properties: A Review

چکیده مقاله

Concrete, which is usually brittle, can be made tougher and more impact-resistant by adding crumb rubber to the mix. In standard concrete, fatigue and impact loads can cause premature failures. Rubber aggregates might help solve that problem. In spite of its loss of some mechanical properties, crumb rubber concrete can be treated using suitable aggregates. The mechanical, chemical, thermal, and microwave treatments can increase the adhesive properties of crumb rubber aggregates. The use of scrap tires for crumb rubber in concrete would have a huge environmental impact since it would solve the disposal challenges and conserve natural aggregate resources in short supply. Although some literature is available on the properties of crumb rubber concrete, it is necessary to evaluate methods to overcome its deficiencies. A major focus of the paper is to examine the acoustic, durability, mechanical, and thermal properties of concrete with untreated or treated crumb rubber. A classification of beneficial treatments is presented. The overall results show that utilizing crumb rubber concrete will help protect the environment and conserve natural aggregates by sustainably utilizing waste material.
