Air Entrained Concrete


Hi all, I've got 3 slideing door sills to pour soon. Of course needs to be air entrained.

I will pay the upcharge to get this delivered if I have to. I was wondering if anyone knows specifically if I can add air to my own mix.

I had a concrete truck driver tell me once it was "just soap" If this is true, anyone know what kind of soap, and how much to add?

Go to your local ready mix company and get what you need. Keep in mind for small a batch,your measurements will have to be precise. I have done this several times myself.

Impeccable source!
Google air entrained concrete.
It would seem to be more than just "soap."

X2, I've done it before by getting a little liquid "air" from the RM supplier. If the dispatcher is willing to work with you, he should have no problem telling you the ratio by weight.

Re: Air Entrained Concrete


Most concrete in areas where the weather is cold will have air entrainer in it. Also you can add your own air entrainer however you would then need to test the concrete to verify the air content is correct.

Re: Air Entrained Concrete


Ahhh, just about pop bottle cap full will do it !!! "natural" concrete without a/e has about 3-4 % air . you want it about 5-7%. I sure as hell wouldn't let that issue hold my job.
