• In order to simulate aging effect on the relationship between penetration resistance qt and liquefaction strength RL in a short time, miniature cone penetration tests and subsequent cyclic triaxial tests are carried out in sand specimens containing fines added with a small amount of cement to make an accelerated test. In contrast to a unique cone resistance (qt) versus liquefaction strength (RL) relationship for specimens without cement despite large difference in relative density and fines content, higher fines content results in higher liquefaction strength for the same cone resistance for sand with cement, which is consistent with the trend found in the field investigation. Thus, it is revealed that the reason why higher fines content leads to higher liquefaction strength does not depend on fines content itself but aging (bonding) effect by fines, which tends to be pronounced as fines increase.
