2014-8-26 At fresh state, the mix design of concrete with recycled aggregates requires an additional quantity of water to obtain a similar workability as a concrete formulated with natural aggregates (Hansen and Boegh 1986). Such a modification may obviously affect the mechanical characteristics of recycled aggregates concrete.

Mix design calculations are conducted assuming aggregates are in a saturated surface dry (SSD) condition, meaning their absorption is satisfied and no water is taken from or added to the mix. If their absorption is not satisfied, these "sponges" steal water from the designated quantity of mix water, reducing the slump of the concrete.
