| 1. | The concrete ’ s anti - frozen can reflect concrete ’ s synthesis durability in the certain degree . this paper changed the former research mentality which enhanced concrete anti - frozen to use an extra material , aimed at the inner mongolian characteristic , utilized compound cement substituted ordinary portland cement , mixed the dula - fiber , the grade 2 inner mongolian pulverized coal ash , the extra material that was highly effective reduces the quantity of water outside the concrete to improve the concrete ’ s main performance , especially the concrete ’ s anti - frozen 混凝土抗冻性在一定程度上能够反映混凝土的综合耐久性能,本论文改变以往提高混凝土抗冻性只采用一种外掺料的单一研究思路,针对内蒙古地区特点,运用复合水泥取代普通硅酸盐水泥,在混凝土中掺入杜拉纤维、内蒙2级粉煤灰、荼系高效减水剂三种外掺料,来提高混凝土的主要性能,尤其是混凝土的抗冻性。 |
