Abstract

This paper describes a basic study on the development of a new test method for determining absorption of fine aggregate. The new method is based on an idea that electric resistance of sand depends on its moisture content. The electric resistance of sand is directly and radically changed by surface water on its particles. It is more obvious when an electrolyte is added to sand.<br>The validity of the electric resistance test results were confirmed by a saturation of interparticle voids of sample. It is also shown that electric resistance is a valid index for judging the state of saturated surface-dry of fine aggregate.
