Failure analysis of the damaged rubber concrete under the secondary load

Failure analysis of the damaged rubber concrete under the secondary load This paper focuses on researching the failure characteristic of damaged rubber concrete under the secondary load. The complete stress-strain curves are obtained from the axial compressive test under the first and the secondary load, and the influence of the incorporation of rubber particles, the particle sizes and the age of rubber concrete on the peak stress, compressive strength, peak strain and limiting strain are discussed, and the difference of the complete stress-strain relationship for the first and the second load is compared. The results show that the damaged rubber concrete still has enough capacity to carry some loads unceasingly, and the better mechanical properties are obtained for damaged rubber concrete with 15% of rubber particles. The deformation values are nearly the same for the rubber concrete under the first and the secondary loads. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Strength, Fracture and Complexity IOS Press

Abstract

This paper focuses on researching the failure characteristic of damaged rubber concrete under the secondary load. The complete stress-strain curves are obtained from the axial compressive test under the first and the secondary load, and the influence of the incorporation of rubber particles, the particle sizes and the age of rubber concrete on the peak stress, compressive strength, peak strain and limiting strain are discussed, and the difference of the complete stress-strain relationship for the first and the second load is compared. The results show that the damaged rubber concrete still has enough capacity to carry some loads unceasingly, and the better mechanical properties are obtained for damaged rubber concrete with 15% of rubber particles. The deformation values are nearly the same for the rubber concrete under the first and the secondary loads.
