poured walls

I am looking to buy Insulated Concrete Form ICF bracing. Anybody have a preference of brand, anyplace sell or rent them near S.C. , thanks for your guidance. I can be emailed at dc7730 at yahoo dotcom

Any negative consequences to high fly ash content in structural concrete? My sub just poured a foundation with 40% fly ash content. I specified 20% -25% because I had heard somewhere that content above 35% can have adverse consequences. Any thoughts, experiences to share?

I am hoping that someone here can help me out. I need to find out how deep someone would need to set rebar into a floor, for a non-loadbearing wall. Looking for code or explicit industry standards, preferably with a citation. Thanks...
