Abstract

Recycled aggregate is an aggregate that satisfies the quality as an aggregate by crushing waste concrete and passing it through a separator. The government grants a floor area ratio of up to 15% and building height mitigation when more than 25% of the recycled building materials are used. In addition to environmental protection issues, it is necessary to actively utilize recycled aggregates that meet the standards to secure the business feasibility of buildings. This study attempted to derive the results according to the substitution rate by measuring the chloride ion diffusion characteristics based on the electrophoresis method.
