Abstract

Acceptance and adoption of prestressed concrete by American railroad industries could provide a great impetus to the advancement of this construction material. Two prerequisites though, are necessary  to make this prediction become a fact, and these are safety and economy. Throughout history, progress in all fields of human endeavor has been the result of factors of human need and economics. It  follows, that progress in industrial enterprises would also be proportioned to the needs and economics of industry. This has been the case of the American railroads and their relationship to the modern design and  use of concrete.
