Abstract:
Rapid drying on the exposed surface of concrete may result in finishing problems such as stickiness, sponginess, and unevenness; plastic shrinkage and cracking; or a compacted surface which creates a layered structure subject to scaling. These undesirable characteristics may be corrected by control of evaporation with a monomolecular film on the surface of bleeding water. Laboratory tests and field experiences are discussed.
