Air Entrainment Test
Air entrainment test is a method used to evaluate the performance of concrete mix and ensure the quality of concrete. It is a crucial step in the production of concrete.
During the air entrainment test, the concrete mixture is placed in a container and mixed with air bubbles using a special device. The mixture is then placed in a water bath to observe the entrainment rate of air bubbles and the degree of dispersion. The test results can be used to determine whether the concrete mix has sufficient air entrainment capacity and whether it can meet the requirements for concrete quality.
In addition to air entrainment test, there are many other methods used to evaluate the performance of concrete mix, such as density test, permeability test, compressive strength test, etc. These methods can be used to ensure the quality of concrete production and ensure the safety of construction projects.
“Air entrainment test”的意思是“空气孕育试验”。
