EFFECT OF WEIGHT REDUCTION ON THE PHYSICO- MECHANICAL PROPERTIES OF CEMENT-RUBBER COMPOSITES FORMULATED WITH SHREDDING OPERATION WASTE

摘要

This study has been undertaken for the purpose of investigating the physico-mechanical properties of rubber dust generated from an aerated cement-rubber composite (ACRC). The volume content ratio of the rubber particles encountered ranges from 0% to 50%. The aerated composite was produced using a new type of proteinic air-entraining agent, in accordance with a specific aerating process derived in the laboratory. This material was developed for use in applications involving cellular concrete. Results from tests performed on fresh aerated composites have demonstrated many attractive properties, such as improved workability and a high stability of air bubbles within the matrix. A study conducted on hardened composite properties has indicated a significant reduction in sample unit weight, thereby resulting in a level of compressive strength compatible with an insulated load-bearing wall.
