摘要
本文详细论述了利用特细砂配置高性能混凝土的施工技术,通过对粗骨料、细骨料、水泥、外掺料等原材料的材质选择,利用三掺技术,改善混凝土的和易性,有效解决了特细砂高性能混凝土的泵送难题。
In this paper, ultra-fine sand in Chongqing and other rich resources of local specialties in detail the use of special sand to configure high-performance characteristics of concrete construction technology, through the coarse aggregate, fine aggregate, cement, additives and other raw materials outside of the excellent choice of material the use of three-doped technology to improve the workability of concrete and effective solution to the ul- tra-high ultra-fine sand pumping concrete issues.
