摘要
堆石混凝土技术是基于自密实混凝土技术发展起来的一种新型大体积混凝土施工技术。在西部偏远地区,粉煤灰资源匮乏,石粉作为掺合料应用于堆石混凝土中可充分地发挥这项技术的优势,本文结合国内某水利工程开展石粉作为堆石混凝土掺合料的试验研究和工程应用可行性研究,研究结果表明:采用石粉可替代粉煤灰生产出满足设计要求的堆石混凝土。
Rock-filled concrete is a new kind of mass concl^te construction technology developed from that of the self-compacting eoncrete. In the remote region of the West China, applying stone powder as admixtures to the rock-filled concrete construction can fully exert the superiority of this technology due to the lack of the sources of flyash therein. In accordance with the construc.- tion of a water works in China, the experimental study on taking stone powder as the admixture for the frock-filled concrete and tile corresponding feasihility study on its engineering application are made herein. The study result shows thai replacing fly ash with stoue powder can produce the rock-filled concrete that meets the design requirement concerned.
