Abstract:
A brief description of the scope of shrinkage-compensating usage in various types of hydraulic structures is given. Effects of shrinkage-compensating concrete on reduction of drying shrinkage stresses, cracking, and water stops as potential points of leakage are discussed. Design considerations by some engineering firms with respect to shrinkage reduction, particularly in circular tanks, are outlined. Construction advantages, such as higher slumps, ease of placement, reduced honeycombing ,and larger placement areas are covered. Durability factors such as freezing and thawing, deicer scaling, abrasion, and sulfate exposure are compared with portland cement concretes.
