With the modern use of basalt stones,we may find that some basalt stones undergo deformation during production.Why is this?Let's take a look together below:
1.Lithology:The basic factor affecting the deformation characteristics of basalt stones.Quartz sandstone,gneiss and other rocks have high hardness and yield strength for elastic deformation,often exhibiting brittle deformation;Various rock salt types such as limestone often exhibit plastic deformation.
2.Moisture content:Pore and fissure water can weaken the chemical bond strength of mineral crystals and reduce the frictional force inside the fissures,so rocks with high moisture content tend to undergo plastic deformation.

3.Surrounding pressure:As the surrounding pressure increases,basalt stones are difficult to break and tend to undergo plastic deformation.
4.Temperature:With the increase of temperature,the elastic limit decreases,and basalt stones quickly enter the plastic stage,exhibiting plastic deformation.
5.The reason for time:The brittleness and toughness of basalt stones vary depending on the length of the applied force.If the stress is applied for a long time,the strain rate of basalt is low,so even hard rocks can be transformed into plastic deformation.Geological processes are often long-term and slow,and even brittle basalt stones can undergo plastic deformation.
The above five factors are the main reasons that affect the deformation of basalt stones.If you want to learn more about related product knowledge of basalt stones,you can continue to follow us.
