Study of Mechanical Properties of Concrete Using Recycled Styrene-Butadiene Rubber (SBR)
Keywords:
Concrete, SBR Rubber, Sustainability, Mechanical Properties, RecyclingAbstract
This research addresses two important issues both locally and globally: environmental pollution and the significant economic return resulting from recycling and reusing materials without the costs of raw materials. One of the major industrial pollutants is waste from automobile tires made of Styrene-Butadiene Rubber (SBR).
In this study, recycled SBR aggregates smaller than 4.75 mm were used as partial replacements for fine aggregate at ratios of 10%, 20%, and 30%. Cement was also replaced with SikaTop-122 at different percentages (3%, 6%, 9%) in concrete.
The mechanical properties of concrete such as compressive strength, tensile strength, and density were investigated. Tests were conducted after 28 days. The experimental results indicated that replacing concrete with recycled SBR reduced compressive strength by 20.31%, 50.19%, and 58.9%, respectively, compared to control concrete, showing a negative impact. However, the replacement reduced concrete density, which contributes positively to producing lightweight concrete
