Abstract

Some of old fluvial sediments are originally composed of fine and silty-clay grains with sands or some of them have been segregated by weathering as a result of the influence of groundwater fluctuations. For this reason, some of old fluvial sediments are not suitable for using as fine aggregates. Furthermore, the old fluvial aggregates with comparatively good quality have been exploited for a long time and quality of most remainders have been significantly poor. Though many old fluvial aggregates do not satisfy the quality controls(QC) standards such as KS F 2526 and KS F 2527, they must be utilized to various usage suitable for different quality categories. Thus, we try
to make constant efforts to utilize aggregates of all qualities. This study shows that physical properties of old fluvial aggregates are both controlled by source rocks and also related to old fluvial environment.

Keywords old fluvial aggregates, groundwater fluctuations, weathering, quality controls, KS F 2526 and KS F 2527
