RS8000 - Rock Test Hammer

RS8000 - Rock Test Hammer

The Proceq RockSchmidt RS8000 is the next-generation digital rebound hammer engineered specifically for measuring hardness, strength, and uniformity testing of rock formations for the evaluation of geological properties. 
 
The RS8000 Rock Schmidt offers superior correlations with Unconfined Compressive Strength (UCS) of Rock, Rock modulus of elasticity (E-modulus), and weathering grades. The RockSchmidt hammer finds application, especially in rock testing applications and penetration rate prediction for tunnel boring machines and rotary drum cutters. 
 
The Rock Schmidt RS8000 has multiple applications and is ideal for companies and organizations involved in geotechnical engineering, mining, tunnelling, civil infrastructure, and geological research. 

• For assessing rock strength and modulus in foundations, slopes, tunnels, etc. 

• To evaluate rock mass properties in open-pit and underground mining operations. 

• For real-time assessment of rock quality and weathering during excavation. 

• For teaching, academic research, and lab-based rock property evaluation. 

• For field mapping, weathering classification and rock mechanics research. 

Additional geological applications include study of the Correlation to unconfined compressive strength of rock / Estimation of weathering grade / Estimation of modulus of elasticity of rock. 

The ISRM & ASTM D 5873, both guidelines have been applied in RockSchmidt hammer for the procedure to determine the rebound number. 
 
RS8000 Ease of use:  Seamlessly integrated with the Rock Schmidt App, users can annotate tests with geolocation, photos, audio, and text while exporting data in PDF or CSV formats. All results can be automatically synced with the Screening Eagle Workspace for cloud backup and global collaboration. 

Equipped with a cutting-edge optical measurement system, the RS8000 delivers impact angle–independent rebound values, reducing operator variability and increasing test reliability.  
 
RockSchmidt Rock test hammer is available in two versions:  :  
a. RS8000 N :  Rock Schmidt Type N has the standardized impact energy of 2.207 Nm. It is ideally suited for field testing. 

b. RS8000 L : Rock Schmidt Type L with impact energy 0.735 Nm is more suited to testing on cores, and bulk rock testing.  

How a Rockschmidt RS8000 Hammer is Utilised: The ASTM D 5873 method requires 10 impacts from which a mean is calculated. Individual impacts that differ by more than ±7 from the calculated mean are discarded and a new mean is calculated from the remaining values. 

Whereas, in ISRM method 20 readings are required with no deletion of outliers. A series may be terminated prematurely if any 10 subsequent readings differ by ±2. On completion of 20 readings the Rock Schmidt calculates the mean and the range.  

When performing rebound hammer test on rock or core samples, both ASTM and ISRM methods recommend the use of a heavy specimen holder to prevent damage to the cores on impact.
