The 2013 edition of the “Dam Concrete” volume consists two parts, “General Requirements” and “Standard Methods”. The newly renamed “General Requirements” has undergone major revisions. Considering the flow from the structural design of concrete dams to their actual construction, a construction planning chapter has been newly added as content that is common to design and construction, and the other chapters were also revised from the viewpoint of their role for performance verification. Passages that featured somewhat difficult to understand or special terminology and expressions have been revised to make them as plain and straightforward as possible. With regard to thermal cracking, the relationship between restraint strain using the restraint intensity matrix method, and the cracking index using the finite element model, was examined and the findings have been incorporated in the revised materials. A review of the influence of minerals, an aspect that requires attention to ensure the physical stability of aggregate, was conducted, and the publication of control standard values was abandoned in favor of the description of appropriate usage methods.
