Abstract: Huangdeng dam is the world’s tallest RCC (roller-compacted concrete) gravity dam under construction with a maximum height of 202 m. Affected by geological conditions and other factors, some engineering problems emerged in the construction process. Such problems include the quality fluctuation of raw materials, the contradiction between new test standard and original design indexes, as well as the coated-powder of aggregate. In this paper, the whole process of solving the above engineering problems by the third party inspection is introduced; the advantage of the third party inspection in additional quality control service is expounded, and the key role of the third party inspection in the quality control of RCC in Huangdeng Dam is revealed so as to offer reference for similar engineering construction.

Key words: quality control, the third party inspection, Huangdeng dam, RCC, coated-powder
