    since i just have a smallish truck and can hardly afford to get a bunch at one time anyway, i thought these might work for me. like make a few at a time till i get the area i want covered (about 23'x45').

    i noticed at least one of them makes pavers about 1.5" thick. does that seem kind of thin?

    My wife was making similar pavers for her garden. I suggested she add the fibers you can buy, to the concrete mix to add some strength.

    Which fibers do you suggest should be used and where can I get them?

    Fibers do not really increase the compressive strength of concrete. They are instended to decrease the micro cracking cause by shrinkage in a poured slab.

    If you do not know what you are doing with them, you can end up with poor concrete. You should really use air entrained cement for durability if you are in a cold climate.

    mudmixer,
    I was thinking about using regular portland cement, wonder what is the air entrained cement, is it special mixing technique or uniqe cement?

    You can buy air entrained Portland cement (Type IA) instead of normal Portland Type I.

    On commercial concrete exposed to freezing, an additvie is used, but that is not usually found in small amounts.

    The air-entrained concrete is much more resistant to deterioration from the alternating feeze/thaw cycles you get in the winter. This is the reason it is required in streets and sidewalks.

    You can use regular portland cement, but air entrained will just last longer.
