People in the construction industry should be familiar with basalt stone.Some users have reported that the moisture content before and after using basalt stone is different.Let's briefly understand the specific moisture content when using basalt stone.
1.We can find that the water absorption rate of different specifications varies during use.It can be observed that the water absorption rate of basalt stones in all specifications is greater than 3%,and the smaller the particle size,the greater the water absorption rate.
2.Before drying,the moisture content of basalt stone is also higher as the particle size decreases.It can also be seen from the table that the moisture content before drying is higher than the corresponding water absorption rate.This is because the water absorption rate was measured according to standard methods,and the sample taken to determine the natural moisture content before drying contains a portion of free water.

3.The average moisture content of the secondary drying is the same as that of the primary drying material,with a specific moisture content of approximately 16.4-21.9%.
4.Although the smaller the particle size of basalt stone,the higher the moisture content before drying.However,whether it is after one or two drying,the smaller the particle size,the lower the residual moisture content.This is because the smaller the particle size,the larger its specific surface area,resulting in greater water absorption or evaporation.
The above introduction is about the comparison of moisture content before and after drying in the process of using basalt stone,which is of great concern to everyone.If you encounter any problems related to stone in the future,remember to consult us.
