Recycled aggregate concrete (RAC) is produced in three major steps: Evaluation of Source concrete: The first step in production of RAC is to determine the quality of the source concrete. Properties and records of source concrete like strength, durability and composition are looked into for deciding the proper source concrete.
The manufacturing process takes 100% curbside recycled glass powder and mixes it with a foaming agent. The mixed powder is sent through a kiln and softened. During this process, the foaming agent creates bubbles within the softened glass and this creates foamed glass aggregates.
