Repairing concrete floor. Advice for method/product.

I have a store room on the side of my home (used to be a commercial building) where the concrete floor has some areas where the top most "layer" has come off probably from water getting in over many years. I am dealing with the water issue by lowering the ground area near the door to drain it off.

I need to fix the floor, though, and that's my reason for posting here. I want to do this one time and I know most pre-mixed products are only good for a few years. The depth of the repair is probably 1/4" - 3/8" or a bit more in most areas and some spots are a foot or more wide.

Can someone give me the formula for the way the old timers used to do it with Portland cement, sand, lime and whatever else to make this a permanent job, please.

Any advice as to how much to mix, whether I can use a 5 gallon pail or do I need a wide trough, all this will be of great help to me for this project.

Thanks for the help.

Edit: Forget about Portland. I got two threads confused.

I've been using a Type S mortar mix with a bonding agent. Cheap mixing pans are available.
