I’m ordering a load of redi mix concrete for an apron. What do I ask for -or- how do I determine which company is supplying the best product? I’m in the upper mid-west, so I’m assuming “low chert”, 6 bag. How about air entrainment, and fiberglass, and slump? I’m using wire mesh and will be sawing in joints. I’ll be pouring in late July (and again in early August) and the site doesn’t get much shade- expecting high temps in the 80’s those days. Thanks!

what quantity.. often times with an apron you will run up against minimum orders ... then your problem will be getting someone to deliver...
3000 # floor mix would be a good choice... keep a low slump... don't add any more mix water than you absolutely have to....
handle and finish it quickly.... and decide how you are going to protect it for curing... poly or spray would be good choices..
*Chris,First of all, check with your local building dept. They will usually spec a minimum PSI (3000 to 4000), minimum slab thickness 4" - 6" and they usually require 6" stone base. Some villages will not allow wire or rebar in aprons or sidewalks on their property (parkway). City crews don't like to hassle with cutting reinforcing when they're breaking out your sidewalks or aprons chasing a water main break.Try for chert free aggregate, (usually a state DOT approved mix) 5-7% air, high range water reducer and a 4" minimum slump at the site. If you spec a state DOT mix with these characteristics, you're usually safe to add 1 gallon of water per yard of concrete, which will give you an extra inch of slump if you need it, without going below spec'd strength. Forget about the fibers; they're unnecessary with a good base, good mix and proper jointing. Probably gonna cost you $85/cy plus extra if Saturday delivery is needed.Don't skimp on the mix quality, and have at least one person help who "knows" concrete. (Even if they just stand there and tell you what to do).
*I do just enough concrete to not quite know what I need to know,you know?. I always give my readymix guy all the pertinent info and he always tells me what I need. Been working with him that way for a while, and Ive never had a problem
