One square of stone is equal to 1.3 tons to 3.0 tons.
The weight of one side of stone is about 1.3 tons to 3.0 tons, which is directly related to the specification of the type of stone, including the size of its particles and density. If the stone is extracted from an ordinary river, 10,000 is about 1.5 tons. If it contains marble, relatively speaking, the density file slightly larger, the weight of each cubic meter is about 2 tons. There is also a kind of granite, its density is relatively large, a party stone weight can be close to about 3 tons.
Stone also has different levels, for example, there are 2 ~ 4, because the density of this gravel is 1300 ~ 1400 kg per cubic meter, so relatively speaking it weighs about 1.3 ~ 1.4 tons. A good quality stone has a density of about 1.5 tons per cubic meter, so it is learned that the weight of each square is about 1.55 tons. Such as granite, difficult to mine, the distance from the ground solid texture, so the density is high, a party weight reaches 1.58 tons.
Stone purchase what are the precautions:
1, from the outside
First of all, in the purchase of stone, can be seen from the appearance of the light color and brightness, good stone gloss is good, and also available tools such as hammer smashing, hard not easy to break the stone quality is higher. At the same time it is best to choose a hit into the stone. Multiple hitting material formed by the poorer stones.
2, according to the stone particle grading and large particle size purchase
Secondly, according to the specific project to choose the stone, such as reinforced concrete structure, you can choose a large particle size and but not more than 40 mm stone; if it is pumping concrete, crushed stone size should be less than the diameter of the conveyor pipe, and pebble size should be less than half of the diameter of the conveyor pipe.
3, pay attention to harmful impurities and needle, flaky particles
Lastly, when shopping for stone, we should look at how the stone content, good stone content are in line with relevant national standards.
