Test method for anchoring agent
2025-04-18
The testing method of anchoring agent is usually different according to its use, performance requirements and construction environment. The following are common conditions of anchoring agents
1. Mechanical testing
1.1 Drawing test
Objective: To test the anchor
How:
After the anchoring agent has cured, tension is applied to the anchor bolt.
Record pull force value ambush bolt out or substrate damage.
Saponification strength is calculated according to relevant standards such as GB/T 50367 or ASTM E488.
Equipment:
Result:
1.2 Shear test
Objective: To detect the anchoring agent on the side
How:
Fix a certain upper limit and apply a shear force at the other end.
Test result
Equipment: shear testing machine
2. Chemical property testing
2.1 Component analysis
Objective: To detect anchors
How:
Use gas chromatography (GC), infrared spectroscopy (FTIR) or high performance chromatography (HPLC) to analyze the composition of the agent solid. 2
Compare product specifications or related standards
Application: The scenario needs to be confirmed
2.2 Chemical corrosion resistance test
Purpose: Comment
Method: 1.
Soak the sample in a chemical solution for a set time and temperature.
Test strength and weight
3. Environmental adaptability test
3.1 Freeze-thaw cycle test
Objective: To test the anchoring agent
How:
will
method
3.2 High temperature performance test
Purpose: Comment
How:
sample
Test its strength
3.3 Aging
Objective: To simulate long-term
How:
Use purple
Detect it
4. Construction performance testing
4.1 Liquidity Test
Objective: To test anchorage
Method: 1.
The tipping fixture is specific to the mold and its flow is observed
Measure the flow radius or flow distance according to the standard.
4.2 Curing time test
Objective: To determine the anchor
How:
The solidifying agent is mixed according to the specification ratio, and the initial and final setting time is recorded.
Compare product requirements and construction conditions.
4.3 Operational time test
Purpose: To ensure that the fixed device is within the operational period
How:
Repeat the test at specified intervals
5. On-site inspection
5.1 Field drawing test
Purpose:
How:
Random inspection of a fixed installation on site.
Using portable drawing test equipment, the tension solution is gradually reached its peak.
