Abstract

Concrete cracking is a major cause affecting the durability and applicability of concrete; it draws increasing attention from researchers in the field of civil engineering. However, previous studies of early micro-cracks are insufficient. The presence of early micro-cracks is the basis of macroscopic cracks. Therefore, a calculation method of internal stress within cement paste caused by core restricted shrinkage under the core restricted condition of rigid body was studied, and a mechanical model of internal stress was established. Based on the model, the factors that affect internal stress within cement paste was further analyzed, and the law of strain variation of cement paste under the rigid elastic body confinement was discussed. The results show practical significance in the control of crack development and in the improvement of concrete durability.
