Shotcrete Penetrometer
Sprayed concrete initial compressive strength tester

Shotcrete Penetrometer accurately measures young concrete resistive force for strength calculation

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).

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. This accuracy—beyond the requirements of the standard—and portability make it ideal for on-site testing.

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. 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 being when the strength is assessed as to be between of 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 hardness. 

Shotcrete Penetrometer provides loadcell accuracy 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 comes complete with all of the accessories needed to measure readings 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.
