Abstract:
This paper is introduced by a brief history of the development of concrete and reinforced concrete since portland cement was first made about 125 years ago. The French are credited with the first use of reinforcement a little after the middle of the 19th century. Widespread use of reinforced concrete be-gan in the United States about 1900. It was first designed by a few specialists, especially in Europe, in accordance with special reinforcement systems. As the art of using reinforced concrete developed, the sufficiency of the resistance of the plain bar to slippage was questioned and attempts were made to deform bars. Laboratory tests of bond were made as early as 1894 but were never extensive. Starting about 1943 the AISI organized a committee of rein- forced concrete research with the object of increasing our knowledge on the effective and economical use of reinforcement.
