A method and apparatus of measuring water percentages of a fine aggregate comprising the steps of prewetting the fine aggregate, containing the prewetted fine aggregate in an air-tightly closed container, applying a centrifugal force to said container over a predetermined period to remove a portion of a quantity of water deposited on the fine aggregate, and measuring the water content remaining in or on the fine aggregate after being subjected to the centrifugal force, and thus determining a percentage of water adhered to the fine aggregate and a percentage of water of the fine aggregate in which interstice thereof is saturated with water while a surface thereof is dry.
