Creep in Concrete

, 2023
Creep in concrete is a long-term deformation under sustained loading. It’s influenced by many factors including constituent materials, environmental conditions among others. Whenever there is an alteration in the convectional concrete preparation process, the creep characteristics need to be realistically assessed.
