Basalt,a type of stone,is quite common in the construction industry.After prolonged use,the surface of basalt stones may exhibit varying degrees of green spots.How did these green spots come about?Why does basalt undergo such changes?Let's take a look together:
1.If the staff does not follow the regulations during work,basalt may undergo changes and may develop green spots.
2.There are also requirements for staff to choose protective agents when using them.

3.Natural pollution may also cause the surface of our basalt stones to develop green spots.In recent years,factory pollution has been increasing,and the air quality is not very good.External pollutants entering the interior of basalt stones may cause green spots.
Basalt stones are becoming increasingly widely used nowadays,but the occurrence of green spots can greatly affect the overall appearance of basalt.In severe cases,it can even affect its normal use.Therefore,we still need to pay more attention when using basalt stones.
