What is the best type of concrete to use for a driveway?
I have to have my concrete driveway redone. Should the the whole driveway be poured with six inches? Or is four inches for the driveway enough and then six inches for the apron?
I am confused on what mixture is best for concrete. A contractor and a building inspector told me fly ash is no good to have in the concrete.
But then according to http://www.flyash.com/, fly ash is good to have in the concrete.
So obviously someone is lying. What is the truth? And what questions do I need to ask to find a competent concrete contractor?
Can anyone give me a reasonable ball park figure as to how much contractors charge to tear out the old driveway, and pour in the brand new concrete, which would also include the rebar and possibly some gravel? Does $4-$8 per square foot sound reasonable?
