Concrete Under Loading Tensile Strength and Bond
Uniaxial impact tensile tests on plain concrete were carried out with the aid of Split Hopkinson Bar equipment with stress rates of up to 60,000 N/square milimeters.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.
