So much to learn and so little time. For more info on the different kinds of Porland Cement and other interesting stuff.  Didn't know that they mixed air into some of it because of freezing and thawing.   Please read the part about too much water.   With all the new posts, and all the new suggestions and materials it is mind blowing what is available for our use.
