- Synopsis
- Most of the construction waste consisting of concrete mass is reused or recycled, although mostly as roadbed material, and only a small portion is currently used as aggregate for concrete. However, maintaining a high recycling ratio in the future will require increased use of waste concrete mass as aggregate for concrete. This paper presents an overview of the results obtained from laboratory tests and on-site tests using actual work equipment carried out to obtain certification by the Minister of Land, Infrastructure and Transport for expanding the scope of application of concrete using recycled coarse aggregate class M to include concrete-filled steel columns and above-ground concrete structures.
- Keywords:
- recycled aggregate class M, recycled coarse aggregate, recycled aggregate concrete, concrete-filled steel column, above-ground concrete structure
