Air Pressure Pin Penetration Testing Machine 'APP Tester'
There are no restrictions on the penetration direction, and in-situ tests can be conducted on the tunnel wall surface.
We handle the air pressure pin penetration testing machine 'APP Tester', which drives a dedicated pin into concrete using air pressure, measures the penetration depth, and estimates concrete strength. This is a simple testing method that replaces the pull-out testing machine used for initial strength testing of sprayed concrete, requiring no test specimens and allowing for in-situ testing of the concrete sprayed on wall surfaces. 【Features】 - Easy to handle with no individual differences in test results - Stable penetration force obtained through air pressure - Allows for a wide range of strength estimation by using two types of pins with different penetration resistances (Pin A: 10–30 N/mm², Pin B: up to 10 N/mm²) *For more details, please download the PDF or feel free to contact us.
