Study on the Properties of Roller Compacted Concrete in the Dam of Jinghong Hydropower Station

Abstract:

For roller compacted concrete (RCC in abbreviation) with the admixtures of limestone powder and water quenched iron slag in dam of Jinghong hydropower station located at the downstream of Lancang River in Yunnan province, the raw materials and mix proportion of the RCC with limestone powder and water quenched iron slag admixtures were studied by materials testing and X-ray diffraction analysis method. Then the mechanical properties, thermal properties, deformation properties and the durability of this RCC were also analyzed by experimental methods. The elastic modulus and creep degree of this RCC were studied specially by the method of experiment and nolinear fitting. The study results show it was theoretically feasible that adopting the double admixtures as the admixture of the mass hydraulic concrete which can be roller compacted concrete. And the properties of this RCC in Jinghong hydropower station meet all kind requirements.
