In our past papers, the state of moisture in an artificial light-weight aggregate used is reported to affect the compressive strength of concrete. This experimental fact may be derived from the different absorption of an artificial light-weight aggregate in fresh concrete and water standardized by an aggregate absorption test. In this report, the absorption of the artificial light-weight aggregate in fresh cement paste is measured and its relation to our proposed "effective water content" that may be able to explain the influence of the state of moisture in an artificial light-weight aggregate on concrete strength is discussed experimentally.
