Abstract

Used tires represent an increasingly serious environmental problem in the United States. This study examines the freeze-thaw durability of concrete with ground waste tire rubber. Various percentages of rubber, by weight of cement, were added to a control concrete mixture. To evaluate the freeze-thaw durability of these “rubcrete” mixtures, freeze-thaw tests in accordance with ASTM C666 Procedure A and microscopic analyses in accordance with ASTM C457 Procedure B, were conducted. Results show that the rubcrete mixtures with 10 and 15 percent rubber by weight of cement are freeze-thaw durable. Results of the microscopic analysis indicate that properties such as air content and spacing factors are difficult to determine accurately because of the problems associated with polishing of the rubcrete specimens.
