The Mortar Penetration Resistance Apparatus, Hand-Held is used to determine setting times of concrete mixes by measuring the penetration resistance. Suitable for lab and field testing, it is ideal for testing prepared mortars and grouts.
A mortar sample, sieved from fresh mix, is placed in a container and stored at a specified temperature. It is tested at regular intervals with standard penetration needles. Resistance is plotted to determine initial (500psi) and final (4000psi) setting times.
The Mortar Penetration Resistance Apparatus is applied using a downward force to penetrate 1in (25mm) into a sample. Pressure is indicated on a scale located on the handle stem via a sliding ring indicator. Unit comes with convenient carrying case.
Includes six standard stainless steel penetration needles with 1, 1/2, 1/4, 1/10, 1/20, 1/40 in² (645, 323, 161, 65, 32, and 16mm²) bearing areas.
