Abstract : The shrinkage effect on concrete is a significant factor in solving the problem of using flexible prestressed ferro-concrete columns and other constructions. This article describes experimental studies of the effect of pre-shrinkage on the stability of concrete columns. The shrinkage of No. 500 concrete specimens was produced by prestressing glass-plastic reinforcement with a modulus of tensile elasticity E sub a 500,000 kg/sq cm and a nominal strength of 13,000 kg/sq cm.
