Study on High Performance Concrete Cracking and Measures for Crack Prevention
Various reasons suggested to cause high performance concrete cracks were investigated, such as external and internal constraints, thermal deformation and creep. Firstly, the real temperature and stress fields simulated were suggested, and then the reasons for cracking and engineer measures for prevention from cracking in high performance concrete were analyzed. The main concept and characteristic of the measures are that the cracking prevention of concrete is a complicated comprehensive problem to be solved by application of combination with different measures in time under construction. The results show that the key economical measures for the prevention are the internal cooling water pipes and external superficial heat preservation. Moreover, the quasi real-time tracking observation, inversion, and feedback analysis under construction are also very necessarily, especially for projects using high performance concrete under severe conditions.
