粉煤灰掺量对混凝土早期裂缝的影响

摘要

This paper researched the amount relationship of concrete early crack resistance performance and fly ash using plate specimen.The test results showed that,with the increase of fly ash,the early crack resistance performance of concrete was raised,finally discussed the mechanism of crack resistance,provided theoretical basis for the application of fly ash.%采用平板状试件研究了混凝土早期抗裂性与粉煤灰的掺量的关系,试验结果表明,随着粉煤灰的掺量增加,混凝土的早期抗裂性得到提高,最后探讨了抗裂的机理,为粉煤灰的应用提供了理论依据。
