Chinese granite suitability?

I bought a load of chinese granite "Bianco Cordo" about 1 cm thick 30 cm x 60 cm.
It's polished white/grey granite. They are placed outside where rain, frost and temperature ranges from -20 (january) to +30 (right now). After having set some plates I noted the granite plane color change slightly. It was probably mortar moisture seeping from below. The polished top did to get any moist. Next day the discoloration has disappeared. It probably just evaporated since its +30 centigrade now.
Will there be problems in winter? Will the granite crack from frost changes? I thought granite behaves well in winter.

I am not familiar with that particular stone, but all stone reacts differently. It's not just whether it is granite or not. I know that some of the Chinese marble has to be installed with epoxy thinset and not regular as the water content messes it up. Marble is not granite, but my point is the same. Ask the supplier.
The darkening from the moisture is to be expected in any stone and most obvious in the lighter colored ones.

The temporary discoloration was hadrly noticeably and it went away quicky so that was not a problem. I don't want the stones to crack, however. I've spent enough time in fixing botched jobs from wrong materials.
The seller of the stones was not sure. They too knew anou the marble. Same thing with some Italian marbles: you have to use same color mortar to be safe.

Since the tiles darkened, they absorbed water. Bad news when it freezes... Unless you seal the whole area religiously you might be in trouble. That might mean every year.

I "I thought granite behaves well in winter."
That's where sand comes from. It naturally spalls and erodes from the surface of granite rocks due to a number of processes of which freeze/thaw is one.
Not to say your stone will fare poorly, sealing it will help ensure the surface stays polished. Cracking should only occur if your substrate is insufficient and moves for amy reason.

All of the china marble and granite i have seen is clearly marked as "Indoor use only". It is low grade and not likely to survive a few freeze thaw cycles. DON'T BUY/TRUST ANYTHING MADE IN CHINA!

Hey put me in the bigot class will you?
If it wasn't pathetic it would be funny. Everyone shopping at Wal-Mart, HD, Lowes, etc. for made-in-China-crap thinks they're a smart shopper. Then they go fill up with gas and bitch like hell because the price is too high and complain about the high cost of housing.
Newsflash: the prices of oil, lumber, Portland cement, etc. are all being driven by Chinese demand.
Buy Chinese goods, pay for them at the pump.

Too true -- and not at all funny.
Far, FAR worse is that fact that with all the money we send them for their goods:
.. They get to build up their military, with which before long they'll be able to drive us out of that part of the Pacific -- and nearby regions of Asia.
.. It's suicide in not just the above way, but also that all that money will eventually get them all driving cars, polluting even worse than they are now, and we over here will also be breathing it!
And trying to survive the rising ocean-levels and everything else that comes from advancing the global warming by what, 20 or 30 years?

How would mother nature know to make inferior rocks in China and superior rocks everywhere else?

Much of everything is manufactured in China, even some of the US flags and US military uniforms if I'm not mistaken. Not everything made in China is bad, some of the tools are actually pretty good and unbeatable at its price point. In some ways our standard of living is better because of the cheap labor but at the expense of factory jobs. I like to bring back manufacturing to America as much as the next guy but how do you complete when our labor rates are so much higher and our quality control, pride and workmanship are not what is used to be and on top of all this stifled by laws, regulations, politicians and corporate greed to save a buck or two?

We can start by spending within our mean.
If US government insists on spending a lot of money and refuses to increase tax, they will have to borrow a lot of money from aboard. And keeping the US dollar very strong is a way to attract foreigners to buy US government debt (then they don't need to increase the interest rate very high). Unfortunately, strong US dollars mean high cost of anything produced in US that has any labor content in it, and this results with losing a lot of manufacturing jobs. This strong US dollars strategy is a sword that cuts two ways. This means we need to get off from this strong US dollar train, and this means foreigners will less likely to buy US government debts, and this also means we need to cut spending or raise tax or both.
Of course, I don't like high tax rate just as much as anyone else. This means we need to cut a lot of spending and cut it very deeply and across the board. And for doing this, we don't need to beg foreign countries to do this and that; this is totally under US control to cut OUR OWN spending.

On top of that... I have to wonder how the hell a ROCK can be "indoor use only".
OTOH, there is one plausible answer to your question: rocks are the same everywhere, but defects may be less likely to be discarded (i.e. more likely to be brought to market) under the Communist economic model (which has been shown in the past to have far less stringent quality standards than the capitalist model).

DG is used a lot for driveways in lieu of ashpalt or concrete around these parts. Poor man's driveway.
Road base is used as well because DG is higher in price. Both work well as they harden up pretty good with rain.
