The ASTM penetrometer resistance test of concrete is a procedure used to measure the rate of hardening of mortars sieved from concrete mixtures. The test is used to determine the effects of variables such as temperature, cement, mix design, additions and ad-mixtures upon hardening characteristics of concrete.
The Acme Laboratory Penetrometer is designed for highly accurate laboratory or field studies. This hydraulically operated apparatus is designed to develop uniformity in complete time-rate-penetration resistance studies of concrete mortar. The unit is supplied complete with six penetration needles.
