In order to ensure maximum strength, verification of consistency is essential in the initial stages of the concrete curing process.
During this phase, multiple needle penetration tests offer a reliable indication of texture, and can be considered in tandem with other tests as the mixture hardens over time.
The shotcrete penetrometer from Mecmesin provides accurate readings of the forces needed to penetrate poured or sprayed concrete during the initial hours of development. This gives a reliable indication of compressive strength and curing progress. The portability and accuracy of the shotcrete penetrometer make it suitable for on-site testing to BS EN 14488-2 (Method A) and used in conjunction with other tests as the mixture hardens over time.

Mecmesin Shotcrete Penetrometer
The Mecmesin Shotcrete Penetrometer is a complete portable system designed for testing the compressive strength of the initial stage of young sprayed concrete to BS EN 14488-2 (Method A). The kit includes:
- 1 x Shotcrete Penetrometer with dual handle (fitted)
- 5 x Rechargeable NIMH Batteries
- 1 x User Guide
- 1 x Operating Manual
- 1 x Mains Charger/Adaptor
- 1 x Carry Case
- 1 x Calibration Certificate
- 15 x Penetration Needles (15 mm needle, diameter 3 mm, top angle 60º)
- 1 x Penetrometer Adaptor
The Mecmesin penetrometer provides accurate low strength data (up to 1 MPa) as soon as you can start testing. This data can immediately be shared with the Shotcrete crews working underground.
The instrument and accessories have brought benefits through easy transportation and has the ability to be used for shotcrete trials, where the samples are shot to be cored at a later date. This has eliminated the need to transport additional samples.
