It is about 1.5~ 1.8 tons. First of all, it should be decided according to the density of the stone. If its density is 1300~ 1400 kg per cubic meter, then one cubic meter is 1.3~ 1.4 tons. If its density is per cubic meter1350 ~1450kg, it is about1.35 ~1.45t..

How to distinguish good and bad stones?

1 First of all, we can judge by the appearance color of the stone. If the brightness is good, its quality will be relatively good. If there is no brightness, then the quality is questionable.

2. It can also be identified by looking at the gravel. If there are more broken stones, the quality will be relatively poor.

3, you can also use a hammer to smash, if it is easy to break, then the quality will be worse, and when the hardness is high, then the stone will be more desirable.

4. It can also be compared by price. If the price is high, the quality will be different.
