Durability of Rubberized Mortar and Concrete

TLDR: In this paper, the durability of concrete and mortar, including aggregate of discarded car tires under environmental conditions, was evaluated using physical, mechanical, and durability experiments on mortar and concrete specimens and it was determined that in the regions where the environmental conditions are not harsh, use of concrete produced with 10% rubber aggregate is appropriate as it is e...

Abstract: This study aims at determining the durability of mortar and concrete, including aggregate of discarded car tires under environmental conditions. These conditions are freeze-thaw, seawater, and high temperature. Concrete specimens produced with a cement dosage of 300, a 0.5 water-cement ratio, and 0, 10, 20, and 30% rubber aggregate in volume, where the grain size is 1–4 mm instead of fine aggregate, and portland compose cement (CEM II/B 32.5) are used for freeze-thaw. The effect of seawater on specimens produced with 10, 20, 30, and 40% rubber aggregate in volume instead of sand was investigated. For specimens produced with 10, 20, and 30% rubber aggregate in volume, the effect of high temperature was investigated. During this research physical, mechanical, and durability experiments were performed on mortar and concrete specimens. As a result it was determined that in the regions where the environmental conditions are not harsh, use of concrete produced with 10% rubber aggregate is appropriate as it is e...
