Analysis of Early Crack at Bottom of Cement Concrete Pavements Slab

Guang-hu Xu, Yuan Shi, Yi Luo

Abstract


During hardening behavior of concrete, shrinkage is induced. While, new poured pavements slab is subject to constraint by subsurface structure which always arouses tensile and shear stress concentration at end-bottom of slab. Employed finite element method, this paper aimed at stress analysis of slab bottom during hardening, and derived the disciplinarian of nonloaded crack formation at bottom of slab.
