Density and absorption of aggregate are important to secure the quality of aggregate and to calculate the mix proportion of concrete. In this report, the history of test methods for them was investigated and the various terms relating to density in ASTM and in Japan were set in order. In addition, the history of standards for density and absorption in Japan were investigated and it became clear that the kind of density for standards changed from oven-dry density to saturated surface-dry density, and again to oven-dry density.
