This early work on concrete-block manufacture is both expensive and hard to find in its first edition. It contains a wealth of information on the science, processes and machines involved in concrete manufacturing. This is a fascinating work and is thoroughly recommended for anyone with an interest in the concrete industry. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
