EFFECTS OF RECYCLED RUBBER PARTICLE CONTENT AS PARTIAL SAND REPLACEMENT ON THE PHYSICAL AND MECHANICAL PROPERTIES OF CONCRETE
Main Article Content
Abstract
The rapid increase in waste tires has posed significant environmental challenges, highlighting the urgent need for sustainable recycling and reuse solutions in the construction industry. This study investigates the effects of using recycled rubber particles derived from waste tires as a partial replacement for natural fine aggregate on the mechanical and physical properties of concrete. Rubberized concrete mixtures were prepared with sand replacement ratios by volume of 0%, 5%, 15%, 25%, and 35%, while the water-to-binder ratio was kept constant at 0.32. The results indicate that increasing rubber content leads to a reduction in concrete unit weight and an increase in water absorption, reflecting higher porosity and a lower degree of compactness. Meanwhile, the thermal conductivity of concrete decreases significantly due to the low thermal conductivity of rubber particles, demonstrating the potential for enhanced thermal insulation performance. The compressive strength decreases with increasing rubber replacement; however, concrete mixtures with rubber contents up to 35% still achieve compressive strengths exceeding 35 MPa. This study confirms the potential use of recycled rubber particles in concrete as an environmentally friendly material for sustainable construction.
