Therefore, once concrete fragments are scattered on the equipment, it will cause great trouble to clean up. Cleaning work is not only time-consuming and laborious, but also easy to cause damage to the equipment, and also affect the subsequent testing work. In addition, the crushed concrete remaining on the equipment may affect the accuracy and reliability of the test results, thereby reducing the accuracy and credibility of the test.
