Can Mix Water Enhancerâ„¢ be used in mixes containing air entrainment chemicals?

(A) Yes. Air entrainment is generally used in concrete mixes to provide improved durability and resistance to freeze-thaw damage, to discourage plastic particle separation or to improve workability. However, air entrainment over and above the actual percentage needed for such improvements, serves only to weaken concrete needlessly.

For example, tests show that air entrainment in concrete mixes without any other mix proportion changes, decrease strength proportional to its air content up to a level of eight (8) per cent. However, Mix Water Enhancerâ„¢ added to mix water, produces concrete that has significantly improved impermeability. Greater impermeability serves to lower, or eliminate penetration of water into concrete.

This reduces or eliminates the need for purposely entraining air for freeze damage resistance. Mix Water Enhancerâ„¢ provides concrete a small amount of purposely entrained air and when combined with the unavoidable incidental air gained during batching air percentage ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
