Description
  • Deicing chemicals are significant corrosion factor in countries with cold winters. This paper is focused on the study of concrete durability, namely its resistance to deicing chemicals that cause concrete scaling. The admixture of metakaolin into plain and air-entrained concrete is described in this study. The experimental part of the work presents results from workability, compressive strength and scaling resistance measurements. It was found that metakaolin improves durability of both normal and airentrained concrete. However, the favourable effect of metakaolin is much more significant for plain concrete. It is concluded that with respect to the results and economical point of view the optimal replacement of cement by metakaolin is 5%. It was also concluded that state of the samples surface that gets tested significantly influences the results. In addition to that, scaling tests are heavily influenced by experimental equipment and operators.
