The resources of natural fine aggregate started to decrease due to the increase in the amount of construction. In addition, it becomes more difficult and less economical to dispose used concrete structure because of the environmental concerns. The use recycled aggregate from the demolished concrete to produce new concrete, therefore, becomes an important issue in the concrete industry. Currently, the recycled aggregates are often used as a source of fine aggregate after some mechanical treatment, but the application to the concrete is limited by the lack of the confidence in the quality of recycled fine aggregate. In most cases, recycled fine aggregate is used as a source of blending fine aggregates, not by itself. Although the standard specification for quality evaluation of the blended aggregates is available, it is still difficult to use blended aggregates in the construction field due to absence of quality management procedure. Therefore, this research especially focuses on the estimation of the properties of the fine aggregate blended by 3 different aggregates. The estimation of properties based on the individual properties of each aggregates was performed using linear interpolation, and compared to the measured values from blended aggregates. The results indicate that the properties of blended fine aggregates can be successfully calculated based on their individual properties.
