巴新NCDC道路改造项目预制圆管干硬性混凝土配合比设计研究

Research on the Mix Design of Precast Round Tubular Dry Concrete for NCDC Road Reconstruction Project in PNG

通过巴新道路项目实例,从原材料选择、配合比试验、指标检测等方面对预制圆管的干硬性混凝土配合比设计进行了研究,提高了预制圆管产品的成管率,保证了预制圆管的高密实度和强度,有力地促进了工程建设。

Mix design of the precast round tubular dry concrete is researched from aspects of raw material selection,mixture ratio test,index testing,through the road project in PNG. The tubate ratio of precast round tubular is improved,and the high density and strength are guaranted. In addition,the engineering construction is effectively promoted.
