Résumé : |
Shrinkage upon drying is an inherent property of concrete. Therefore concrete structures are prone to undergo considerable shrinkage within a few months, and they usually crack to relieve the tensile stress induced under restraint. Shrinkage-compensating concrete (SCC) eliminates unsightly shrinkage cracks, thereby improves durability, serviceability and reduces maintenance cost. |
