The VFG Shotcrete Penetrometer is Mecmesin's specialised test kit designed for use in testing sprayed or poured concrete during the first few hours of development. It meets the requirement principle of the industry standard EN 14488-2 Method A: Penetration needle to measure penetration resistance force
Featuring a touchscreen display showing readings in N, it allows batch testing with each result being automatically converted into MPa according to the size of the aggregate being tested. Converted MPa readings are displayed as a table on the VFG Shotcrete Penetrometer for immediate review.
The AFG Shotcrete Penetrometer is Mecmesin's specialised test kit designed for use in testing sprayed or poured concrete during the first few hours of development. It meets the requirement principle of the industry standard EN 14488-2 Method A: Penetration needle to measure penetration resistance force
It features a membrane keypad and LCD display with readings in N or daN. Readings can be stored to memory and later exported to a PC for spreadsheet analysis to perform the conversion into MPa as required by EN 14488-2.
The Shotcrete Penetrometer is a complete portable system for testing the compressive strength of the initial curing stage of young sprayed concrete to BS EN 14488-2 (Method A).
Available in 2 versions it provides accurate readings of the forces required to penetrate sprayed (shotcrete) or poured concrete. These resistive force readings are then used to convert to a compressive strength value. The accuracy of both versions surpasses the requirements of the standard and their portability makes them ideal for on-site testing.

Overview
The Shotcrete Penetrometer is Mecmesin's specialised force test kit designed for use in testing to the international industry standard relating to sprayed concrete or poured concrete during the first few hours of development. Available in 2 versions this instrument meets the requirement principle of Method A: Penetration needle to measure penetration resistance force.
Testing to BS EN 14488-2 (Method A)
Verification of consistency is vital in the initial stages of the concrete curing process in order to ensure maximum strength. This phase is defined as when the strength is assessed as being between 0.2 MPa to 1.2 MPa.
The standard Testing sprayed concrete – Part 2: Compressive strength of young sprayed concrete indicates the testing procedure to be used; multiple needle penetration resistance tests, which provide a reliable indication of compressive strength.
Shotcrete Penetrometer features an accuracy of ± 1N, far exceeding the recommendation of the test standard, and can be used in conjunction with other tests as the mixture further hardens over time.
Complete on-site testing kit
The portable Shotcrete Penetrometer kit is available in 2 versions.
The VFG Shotcrete Penetrometer features a touchscreen display showing readings in N. It allows batch testing with each result being automatically converted into MPa according to the size of aggregate being tested (as per EN 14488-2). Converted MPa readings are displayed as a table on the VFG Shotcrete Penetrometer for immediate review.
The AFG Shotcrete Penetrometer features a membrane keypad and LCD display with readings in N or daN. Readings can be stored to memory and later exported to a PC for spreadsheet analysis to perform the conversion into MPa as required by EN 14488-2.
Both versions come complete with all the accessories needed to conduct penetration tests and calculate strength values at the construction site. This enables quick turnaround of results at this time-sensitive phase of strength development and helps determine whether it is safe to re-enter tunnels and resume blasting near the shotcreting site.
