生态混凝土在青藏高原地区的试验研究及工程应用

Eco-concrete experimental study and project application in Qinghai-Tibet plateau

通过进行试验室和青海省西宁市湟水河河道治理工程现场试验,研究了骨料种类与级配、水泥用量、水灰比、SR-3和SR-4添加剂的选用及掺量比例对生态混凝土性能(强度、孔隙率、透水系数、酸碱度等)的影响,在试验和分析的基础上开发出适合于高原严酷环境的具有护坡、植生等功能的生态混凝土。

Through test in the laboratory and at the river training projects field of Xining Huangshui river of Qinghai Province, the type of aggregate and grade,the cement content, W/C ratio, SR-3 and SR-4 chemical admixtures selects and mixes the quantity proportion to performance influ ence of eco-concrete（ strength, hole ratio, water percolation coefficient, acidty and alkalinity ect was studied ）.Based on tests and analysis, eco-concrete is developed, that has slop protection and plants functions,it suits to the plateau of severe environment.
