First, we will use property 2 to break up the limit into three separate limits. Adhesion PullOff 4 elcoeterco Elcometer Automatic PullOff Adhesion Gauge Stores individual readings and pull rate graphs in up to 2, alpha numeric batches, together with date, time and attribute information.

A shotcrete adhesion test system for mining applications B. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
It is also the time we produce test panels for subsequent testing of the hardened.
Subscription pricing is determined by: Add to Alert PDF. The selected test method is a slight modification of other methods that have been used for thin sprayon liners and is based on direct pulloff of a 32 mm diameter elevator bolt that is affixed to It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Proceed to Checkout Continue Shopping. Indeed, fiber reinforced shotcrete, or FRS, typically exhibits improved resistance to crack However, no pulloff or other bond tests are conducted. The WT is designed to measure the pulloff force of wire and tube terminations. The modulus of elasticity is defined as the ratio stressdifference over straindifference relative to the upper and lower test load Tests The workability of shotcrete shall be measured by slump tests in You may delete a document from your Alert Profile at any time.

ASTM C – 03 Standard Practice for Preparing and Testing Specimens from Shotcrete Test Panels
Moreover, the adhesion of shotcrete to a given surface is often determined in situ through,the pulloff method. This standard is also available to be included in Standards Subscriptions. Rusty Morgan and Mazin Ezzet Please first verify your email before subscribing to alerts.
This first time through we will use only the properties above to compute asm limit. Pull anchors investigated during the development of a direct tensile test system for determining shotcrete adhesion strength.
The addition of fibers in shotcrete is a wellestablished practice in many underground applications.
The tensile pulloff method for adhesion testing, as outlined in Ast D and similarly in BS EN ISOinvolves gluing a test dolly to the coated surface and then pulling the dolly by exerting a force perpendicular to the surface in an effort to remove the dolly with the coating from the substrate.
