| Abstract: | Mineral admixture is one of the necessary compositions of the high performance concrete.This test shows that adding heterogeneous mineral admixtures to the concrete can availabley decrease the porosity of the paste and improve the pore-size distribution,as well as enhance the frost durability of high performance concretes. |

| Keywords: | pore-size distribution mineral admixture freezing and thawing cycles durability |
