Disadvantages of Air-Entrained Cement
- The strength of concrete decreases.
- The use of air entraining agent increases the porosity of concrete thereby reducing the unit weight.
- Air-entrainment in concrete must not be done if the site control is not good. This is due to the fact that the air entrained in a concrete varies with the change in sand grading, errors in proportioning and workability of the mix and temperatures.
