Any advise on concrete mix for a new deck I am going doing myself. Deck size is just 2' all around a 20x40 vinyl inground. about 3 yards.
3500 psi should be good. I need to order with these instructions.
1. How about Liquid Chloride % ?
2. slump?
3. Air or fiber mesh?
4. Do I use foam expansion joints around the fiberglass stairs?

any advise would be appreciated.

Thanks
Jd
