The use of preplaced aggregate concrete, also known as PAC, is a well-known concept. It is a method of placing concrete that has been around for many years. However, using PAC to repair underwater bridges and dams has only recently become commonplace. There are a variety of advantages to using PAC in bridge and dam repair: Less Cracking When placing PAC, a higher ratio of aggregate to cement is achieved due to the process in which it is placed into the formwork. The aggregate is put into the form, and then the grout is injected in increments. This can significantly reduce the amount of shrinkage that would normally occur in traditional repair methods. The reduced shrinkage leads to a higher bond with the concrete surfaces that are already present in the structure. This higher bendability and reduced shrinkage results...
