The purpose of this study is to establish the technique that can be evaluated in the properties of the concrete using aggregate performance and mix proportions as indicator. In this paper, the application as indicator for aggregate performance of aggregate crushing value, sinkage of plunger (aggregate sinkage) and abrasion loss were investigated by results of experiments using recycled fine aggergate mortar. From this experimental results, aggregate crushing value and aggregate sinkage could apply as the indicator for aggregate performance. Compressive strength and drying shrinkage of recycled fine aggregate mortar could be estimated by using that indicator. To apply elastic modulus of aggregate and aggregate shribkage calculated from theoretical formulas as indicator were effective means, in addition to that indicators.
