| 摘 要： | 本文研究了粉煤灰掺量在40%～60%的大掺量粉煤灰混凝土的力学性能及若干耐久性性能。试验结果表明,添加了40%以上粉煤灰的混凝土仍有较好的强度,较好的抗氯离子渗透、抗硫酸盐侵蚀等性能,且具有较小的体积收缩率。同时,大掺量粉煤灰混凝土的后期强度增长对于混凝土的意义也不容忽视。

| Abstract: | Mechanical properties and durability of high volume fly ash concrete which contains 40 to 60 percent of fly ash by weight are studied in this paper.The results show that concrete with 40 percent fly ash has good properties of strength,resistance permeating of Cl-and resistance erosion of sulfate.Besides,it has a small shrinkage ratio.The increasing ratio of the later strength of high volume fly ash concrete can't be ignored,too. |

| Keywords: | high volume fly ash concrete durability later strength |
