The factors that influence the amount of air entrainment are: 1. Type and Amount of Air Entrain Agent 2. Water Cement Ratio of the Mix 3. Type and Grading of Aggregates 4. Mixing Time 5. Temperature at the Time of Mixing 6. Type of Cement 7. Compaction 8. Influence of Other Admixtures 9. Effect of Hard Mixing Water 10. Effect [...]

In this article we will discuss about the effects of air entrainment on the properties of concrete. 1. Effect on Resistance to Freezing and Thawing: The high resistance developed in the hardened concrete to scaling due to freezing and thawing is the greatest advantage of air entrained concrete. It is observed that when an ordinary concrete is subjected to a [...]
