SC-55 Type Free Swell Meter
The rock free expansion testing instrument is suitable for determining the expansion properties of rocks containing easily water-absorbing and expanding minerals in their natural state, such as clay rocks. This test is the ratio of the radial and axial deformation produced by the specimen after water immersion to the diameter and height of the specimen, expressed as a percentage. It conforms to the following standards: GBT50266-2013 Standard for Engineering Rock Mass Test Methods; JTGE41-2005 Highway Engineering Rock Test Regulations; SL264-2001 Water Conservancy and Hydropower Engineering Rock Test Regulations; DLT5368-2007 Water Conservancy and Hydropower Engineering Rock Test Regulations; TB10115-2014 Railway Engineering Rock Test Regulations.
