高石粉人工砂原级配混凝土干缩性能试验研究

Experimental study on dry-shrinkage property of fully graded concrete with high powder-content artificial sand

结合水电站建设工程 ,对高石粉人工砂原级配大尺寸试件混凝土干缩性能进行了试验研究 ,探讨了人工砂中石粉含量、骨料级配、试件尺寸等对混凝土干缩性能的影响以及相关性分析 ,其结果对工程建设具有参考价值 .

For construction of hydropower stations, experimental studies are performed on the dry-shrinkage property of large-scale fully graded concrete specimens with high rock powder-content artificial sand. Test results indicate that the content of rock powder in artificial sand, aggregate grading, specimen dimension, etc. have significant effects on the dry-shrinkage property of concrete. Based on test results, correlation analysis of those effects is carried out. The results may provide a reference for project construction.
