碾压混凝土渗透溶蚀耐久性的研究

Studies on the Durability of Permeasible Corrosion of Roll Compacted Concrete

本文结合 2 0 0 m级高碾压混凝土重力坝实际工程 ,阐述了粉煤灰混凝土抗渗、溶蚀性能的稳定性。通过对不同配合比混凝土中主要物质累计溶出量的计算及耐久性预测 。

In connection with practical engineering of2 0 0 m roll compacted concrete dam,this paper describes the stability of permeable corrosion of flyash concrete. By calculation of the accumulative amount of corroded substance in the concrete of various compositions and by durability prediction,we obtained the limiting amount of flyash aceeded to the roll compacted concrete.
