Teach you to distinguish the quality of sand and gravel for building.

We all know that building houses can't be separated from sand and gravel, and the use of sand and gravel in buildings is particularly important. Without sand and gravel, it is impossible to build houses or industrial houses. At the same time, we often have such a misunderstanding that sand and gravel are not components of sand and stones, so just buy these things and use them. In fact, the quality of sand and gravel is also divided into good and bad, so how can we distinguish the quality of sand and gravel in buildings?

At first, people used natural stones, such as pebbles, in small quantities, but the quality was also different; The other is some pebbles produced by mountain blasting, or those smashed by hand with a hammer, but these costs are quite high. With the development of social science and technology, professional production equipment has appeared. The material produced by this equipment is not only efficient, but also greatly reduces the labor cost, thus reducing the production cost. With the mechanized production, from the transportation of raw materials to manufacturers, it is first big and then small.

After layers of screening, materials with different sizes are selected and then transported to the market to complete the whole production process.

How should we distinguish the quality of sand and gravel? We all know that it is difficult to strictly distinguish the quality of stones, only roughly. For example, we can judge whether they are good or bad according to their appearance, which mainly depends on their appearance quality. Brighter ones will be better, darker ones will be worse. In addition, it can also be observed and analyzed according to the proportion of crushed materials. When cleaning manually, you can see that the broken materials are of poor quality. In fact, the easiest way to distinguish the quality of sand and gravel is to beat it with a hammer. The harder you work, the better the quality, and vice versa. So, what caused their inconsistency in quality?

The main factor affecting its quality is the quality of raw materials. The higher the hardness of raw materials, the better the quality, and the better the quality, and vice versa. At the same time, it will also be affected by machinery. The better the mechanical properties, the better the materials produced, so it is also very important when choosing machinery.

Besides, when we buy sand and gravel, we must look carefully.

Distinguish whether the good material is the raw material you choose, and see if it is mixed with other materials, so as to avoid these accidents affecting the quality of aggregate.
