This paper focuses on the influence of type and moisture states of recycled concrete aggregates on the properties of fresh and hardened concretes. The test results showed that the initial slump of concrete mixtures depends on the amount of initial free water, and the slump loss of the mixtures depends on the type and the moisture state of the aggregates. The most notable observation made was that the concrete mixture using 100 percent OD recycled aggregate displays the highest rate of slump loss. Compressive strength of the recycled aggregate concretes prepared decreases from 15 percent to 33 percent compared to that of normal concrete. The highest compressive strength of concrete is achieved with using I/2SSD,RCAs the values. However, The SSD recycled aggregates seemed to impose the largest negative effect on the concrete strength, which might be attributed to "bleeding" of excess water in the prewetted aggregates in the fresh concrete.
