再生骨料级配对再生混凝土多孔砖干燥收缩的影响

Effect of aggregate gradation on drying shrinkage of recycled concrete perforated brick

对不同碎砖和细骨料含量的再生混凝土多孔砖进行干燥收缩率试验研究。结果表明,再生混凝土多孔砖干燥收缩率随碎砖骨料掺量的增加而增大,随着细骨料掺量的增加而减小。

The drying shrinkage of recycled concrete perforated brick with different content of broken bricks and recycled fine aggregate was tested. The test results show that the drying shrinkage of recycled concrete perforated brick increases with the raising of broken bricks content, and decreases with the raising of recycled fine aggregate content.
