Faculty Civil Engineering and Geosciences Department Stevin Laboratory Date 1982-01-01 Abstract Uniaxial impact tensile tests on plain concrete were carried out with the aid of Split Hopkinson Bar equipment with stress rates of up to 60000 N/mm2. s. Various concrete mixes were investigated under. dry and wet conditions. All the concretes showed an increase in strength with increasing stress rate. At very high stress rates the strength may attain twice the static tensile strength. Repeated impact tensile loading reduces the strength considerably more than cyclic loading does with conventional stress rates. The bond between reinforcing steel and concrete was studied in pull-out tests with short embedment length. The results showed the bond strength and stiffness of deformed bars to increase with the loading rate, whereas plain bars and prestressing strands were hardly affected by the loading rate. It proved possible to formulate the tensile strength and the bond behaviour as a function of stress rate by means of a power function. Relations between compressive strength and tensile strength are given for various stress rates.
