air-entraining cement
Quick Summary
Air-entraining cement is a type of cement that incorporates minute air bubbles into concrete or mortar. This is achieved by adding a small amount of an organic agent, typically about 0.05 percent, during the grinding process.12
The primary benefit of air entrainment is increased resilience and resistance to wear and weathering, particularly freeze-thaw damage in cold climates. Air-entrained concrete is also generally easier to work with. This special type of cement is one of several standardized types of portland cement, which forms the basis for many building materials.12
