Physical and mechanical properties of foamed Portland cement composite containing crumb rubber from worn tires
Highlights Crumb rubber was used as lightweight aggregate in Portland cement mortar. Air-entraining agent improves the workability and ensures a cellular structure. Minimum required compressive strength for construction materials was achieved. Construction applications for the foamed rubberized mortar are proposed.
Abstract The management of worn tires is a concern in industrialized countries. The application of crumb rubber as lightweight aggregate in cement based materials is a green alternative for reusing this material. High replacements of natural sand by crumb rubber were studied and an air-entraining agent was employed to ensure a cellular structure in the cement-based composite. The obtained results from tests in fresh state reveal an improvement in workability. The tests conducted on hardened composite show promise for constructive applications where thermal and acoustic properties are required. The minimum requirement of mechanical strength for masonry units was achieved, since compressive strengths varied between 1 and 10MPa. Finally, potential applications as a construction material have been highlighted.
