Abstract:
The mechanical and physical properties of concrete specimens obtained from replacing natural coarse aggregate with waste vehicle
rubber tires at levels of 2vol%, 5vol%, 7vol%, and 10vol% were studied, and the corrosion behavior of reinforcing steels was investigated
in these specimens. Corrosion rates were determined by measuring the galvanic current between steel-reinforced concrete specimens both
with and without chloride addition. The change in electrode potential of reinforcing steels in these concrete specimens was measured daily
for a period of 60 d in accordance with the testing method in ASTM C876. The results show that the use of waste vehicle tires in concrete instead
of coarse aggregate decreases the mechanical strength of the specimens, and increases the corrosion rates of the reinforcing steels embedded
in the concretes.
