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.
