Abstract: The use of pervious concrete has been rapidly growing as a means to meet burgeoning stormwater regulations. A difficulty in placement of pervious concrete has been the need to rapidly cover the material after placement and leave it covered for seven days to ensure moisture is not lost and the cement paste fully cures. Surface unraveling is a common cause of failure of pervious concrete installations due to rapid moisture loss from the cement paste of the freshly placed pervious concrete mixture. By adding to the pervious concrete mixture an internal curing agent which holds and releases moisture in a controlled manner to the cement paste as it cures, the likelihood of under-cured cement paste and surface raveling of the pervious concrete is greatly reduced. This invention comprises materials and methods for their use which provide a source of moisture with controlled release for curing of the cement portion of pervious concrete.
