1. Conceptually distinguish between gravel and crushed stone:

Gravel gives people the first impression that it is small and a little messy, while gravel is often associated with water or rivers. If we distinguish between gravel and gravel conceptually, they are better than gravel and pebble, because gravel often has sharp edges and corners, which are mostly formed by weathering and crushing of rocks and produced in mountainous areas; However, gravel is a kind of stone without edges and corners. It is a stone that has been washed and polished by waves for a long time and is produced in rivers. You don't need to compare carefully, you can tell what stone it is just by looking at whether the stone has edges and corners.

2. Distinguish the difference between gravel and crushed stone from the construction characteristics:

Gravel is smooth and flat without edges and corners, but after years of surfing, its hardness is not as good as gravel, which also determines that it is a low-strength stone in architecture. In addition, due to the smooth shape of gravel, when it is used with cement in construction, its adhesion to cement slurry is not as good as that of rough gravel, which also causes poor construction stability. For example, in construction projects, where the requirements for strength and bearing capacity are high, gravel is needed, and gravel is prohibited. Gravel has good hardness and strength, is relatively uniform, has sharp edges and corners, can closely adhere to cement, and is much stronger than gravel. In some high-grade concrete, it is stipulated that only macadam can be used, not macadam. In fact, the difference between gravel and gravel, the difference between pebbles, is mainly caused by their different cohesive force with cement in engineering.

Crushing stone

The difference between gravel and pebble

Conceptually distinguish gravel from pebble;

Gravel and crushed stone are often used in general building construction, but pebbles are also used. Because pebbles are as smooth as gravel, the bond with cement is not very good. Gravel and pebble are closely related to weathering and water impact, so there is little difference between gravel and pebble. Some big pebbles are broken into small pebbles, one side is rough and the other side is smooth, which can also be called gravel, and pebbles are pebbles with smooth surfaces and no edges and corners.

In the process of building construction, crushed stones, crushed stones and pebbles will be used, but because of their different stone characteristics, their proportions in use are also different. If you want to choose and use it skillfully, you must understand the difference between gravel and gravel, and the difference between gravel and pebble.
