Influence Analysis of the Incorrect Construction Sequence on Concrete Strength of Cast-in-Place Piles

Abstract:

The core drilling method is used for testing the concrete strength of the cast-in-place piles during the construction of a power plant. The concrete strength of some cast-in-place piles is far lower than the normal expected value. The incorrect construction sequence is the main cause of the quality problem. It is inadvisable to shorten the time limit for a project while ignoring the project quality. The more time will be spent to solve the quality problem of the project after the construction is complete. The construction organization is important for the quality of the projects and the reasonable construction sequence can improve the project quality.
