WebWhen you pump air entrained concrete one of three things will happen: 1. The air will go down 2. The air will go up 3. The air will stay the same - Ken Hover Most people are … WebThese air pockets relieve internal pressure on the concrete by providing tiny chambers for water to expand into when it freezes. Air-entrained concrete is produced using air-entraining portland cement, or by the introduction of air-entraining agents, under careful engineering supervision, as the concrete is mixed on the job.

WebJun 29, 2024 · An air-entrained mix is best to use for concrete projects where the surface will be exposed to the freeze-thaw cycle during the winter months. Even in climates where the winters aren’t as harsh, but still reach occasional temperatures below freezing, using air-entrained concrete is a safe idea. Air entrained mixes are not all-purpose! WebFinishing Air-Entrained Concrete. Used in many applications, air-entrained concrete uses a chemical admixture (or sometimes, air-entraining cement) to produce a system of small voids during the mixing process. These voids are stabilized by the air-entraining admixture and remain in the hardened concrete paste. brave dublat
