Concrete MixPosted by Edwin (70.89.248.189) I am about to stack and fill the support blocks. I was looking at using a Concrete Mix instead of buying the raw ingredients. Yes, I know it will cost more, but storage space and transportation are an issue. So when Rado's directions call for a 4-1-1 can I just add lime to the mix? If so, how would I calculate the amount to add? I will be using the 40Lbs bags. Concrete Mix |
