What is the difference between natural pebbles and machine-made pebbles?
How are two kinds of stones formed
1.Machine-made Pebble Stone
Machine made pebbles can be divided into machine grinding or manual bonding.
Machine grinding:The edges and corners of the crushed stone are polished into a smooth and non-angular shape. Compared with natural pebbles, the oiliness is far worse, and the SiO2 content of natural pebbles is also relatively high.
Manual bonding: The shape can be controlled at will, and the oil smoothness can be a regular circular sphere, but the compressive strength of the finished product is not as good as that of natural pebbles .
2.Natural Pebble Stone
The formation of natural pebbles is a long process, which can be washed by river water or rubbed against each other. Your pebbles may be made up of historical floods and mudslides (because they are in the mountains), but the specific reasons depend on the geological structure and geographical environment there, as well as the conditions of other surrounding mountains. As for the mountain that does not grow trees, it may be caused by the soil or the contact between the surrounding tree species and organisms.
In the Mesozoic era about 100 million years ago, under the effect of crustal movement, magma emerged from the surface, and the rapidly cooled magma formed granite. Thousands of years ago, the granite was squeezed and dislocated due to magma invasion, and then a large number of smaller stones were produced. Rolling, eventually constitute today’s pebbles.
Uses of two types of stones
1.Machine-made Pebble Stone
The pebbles of the mechanism are generally used for laying on the walls and floors of outdoor construction.
Color-treated pebbles are generally used indoors as decoration decoration for some parts.
2.Natural Pebble Stone
Natural pebbles are taken from the river bed, after cleaning, screening, sorting and other processes, they are widely used in public construction, villas, courtyard construction, pavement paving, park rockery, bonsai filling materials, garden art and other high-level upper-level constructions. It not only promotes the old civilization of the East, but also embodies the classical, elegant, and authentic style of the West.
