Design of filling self-stressing concrete to use in strengthening of columns by prefabricated jacketing

Abstract

h i g h l i g h t s A design and characterization of an self-stressing SCC is offered. An improved alternative for the reinforcement of pillars by confinement is proposed. Turning the reinforcement action from passive to active from casting is proved. A double-ring test device determine effectively the expansion of the concrete. The double-ring device eliminates the dependence of the setting time from ASTM C878.
