Abstract:
There is probably no branch of the concrete industry where the application of scientific principles can be of more value than the production of machine made concrete pipe, and there is probably no class of concrete concerning which so little is known as the very dry mix material which the pipe manufacturer compacts in the desired form by use of packer head, tamper or centrifugal mechanism. During the past two year conditions apparently brought about by the condition of the concrete previous to the placement have been brought to our attention.
