A series of cyclic loading tests and unconfined compression tests were carried out for the foamed mixture cement soils with an air containing ratio of less than 50%. As the results, it was shown that the foamed mixture cement soil did not decrease its strength even after 80000-cyclics loading. However, the unconfined compressive strength decreases gradually and the secant modulus of elasticity decreases drastically with increasing number of dry-wet cycles. Therefore, it is important to take the decrease of secant modulus with the increase of dry-wet cycles into consideration in case of usage at the depth of the groundwater table.
