平板法在掺锂渣高性能混凝土抗裂方面的应用

摘要

采用正交试验法,通过平板开裂试验研究了不同掺量锂渣对混凝土塑性收缩、自收缩裂缝的影响,结果表明：锂渣混凝土早期裂缝的最大宽度、总长度以及总面积随锂渣掺量的增大而趋于减少。%Using the orthogonal test method,through the flat band cracking test,this paper researched the influence of lithium slag mixed to concrete plastic shrinkage and since the shrinkage crack.The results showed that：the increase of lithium slag mixed was accor
