摘要
Abstract
The concrete used inDahuaqiao Hydropower Station Project employs limestone manufactured sand.Affected by the inherent properties of raw materials and long-distance transportation,the conventional sand exhibits elevated fines content and increased water demand.To ensure the construction quality of architectural concrete,extensive mix proportion trials were conducted to develop a high-fines-content architectural concrete mix.Through meticulous analysis and control of construction technical details including formwork design,visible joint and Zen joint arrangements,internal corner treatments,and concrete pouring procedures,the architectural concrete components at Dahuaqiao have become one of the quality highlights of the entire project.关键词
