Determining the Surfactant Consistent with Concrete

Determining the Surfactant Consistent with Concrete

Info

To protect concrete from F-T damage, a soap or surfactant, called an air entraining admixture (AEA), is added while the concrete is mixing. An AEA helps stabilize air-voids that are spherical and typically between 0.0005” and 0.05” in diameter. After the
