万安水利枢纽碾压混凝土性能研究

Properties of Roller Compacted Concrete Used in Wan'an Project

万安水电站二期主体工程溢流坝6～15坝段、左岸非溢流坝5坝段和左导墙部分拟采用碾压混凝土筑坝技术。本文应用正交设计法对碾压混凝土的配合比及其物理力学性能进行了较系统的试验研究。

Roller compacted concrete (RCC) will be used in section No. 6-No. 15 of the spillway dam, section No. 5 of the non - overflow dam near the left side bank and the left guide wall of Wan'an Project. Using orthogonal testing method. selected the mix proportions of RCC were conducted. This method not only can reveal the relationship between the properties and mix proportions, bur also can provide audio-visual results, and thereby optimizes the mix proportions of RCC satisfying the de sign demands.
