Unfortunately, concretes at low w/c are prone to cracking at early age unless special precautions are taken. Because these mixes have relatively low water content and, therefore, less drying shrinkage, experts have had to look elsewhere for an explanation. During the last decade attention has focused on a well-established, but little-known phenomenon: autogenous shrinkage.
