Original Abstract

In current concrete practice, several types of air entraining admixtures are used. These admixtures aim to improve the durability of concrete in aggressive exposure conditions caused by negative temperatures in combination with salts. The current article attempts to describe the types actually used, namely, synthetic tensides and natural resins and to also compare their effect on the durability of physical and mechanical parameters. With these admixtures, air entrained concrete with different amounts of air content in the concrete are designed. Furthermore, the article describes methods for determining the parameters of air entrained concrete, as well as their advantages, disadvantages and their evaluation.
