Query: Very Badly Written

Like all of Professor Nawy's books, this one is extremely badly written. There are numerous typos and mistakes, although some are kind of entertaining. The Reinforced Concrete Book for example discusses the "modulus of rapture" of concrete. The chapter on Unbonded Post-tensioning in the Concrete Construction book discusses "prostrating tendons".This is probably not a bad book for an experienced engineer, and might even be considered a useful exercise, since nothing in the book should be relied on without checking at least one other reference. It is not a book that should be used to learn prestressed concrete design however.
