《南水北调与水利科技》：南水北调工程高性能混凝土原材料优选试验研究（韩玉莲,王铁强,张雅娟,张昀保,张玮,潘全路）（摘要

摘要：结合南水北调中线工程河北段渡槽槽身预应力混凝土的性能指标要求，通过对石家庄及以南地区的混凝土原材料部分生产厂家的调查，进行了水泥、掺合料、外加剂、骨料的初选试验，经过进一步的优化试验、分析比较，提出了在满足设计及施工要求的前提下，本着因地制宜、就地取材的原则，优选出了品质优良、货源充足、技术先进、经济合理的混凝土原材料。

Abstract:Initial sorting tests of cement,admixtures,additives and aggregates have been conducted on investigating partial manufacturers of the raw materials for concrete in shijiazhuang and the regions to its south,about the performance index requirements of the prestressed concrete for aqueduct bridge body of Hebei section of the South-to-North Water Diversion Project (Middle Route).By further optimized tests and analytical comparisons,the principle of treatment with local conditions and abtaining raw materials locally has been presented on the premise of meeting the requirement of design and construction,and economic,reasonable and optimized raw materials of high quality,sufficient supply and advanced technique for the concrete have been selected.

Key words:concrete;raw material;optimize experiment
