Hydraulic reaction-type apparatus for determining the time of setting of concrete with slump greater than zero by testing motar sieved from the concrete mixture. Unit also determines effects of variables such as temperature, cement, mixture proportions, additions and admixtures upon the time of setting and hardening of concrete.
Penetrometer's new design makes it easier to operate, more efficient, with a longer gear rack. All needles are one length so settings may remain the same. Loads are applied hydraulically with pressures read on a 200 lbf (890N) capacity gauge graduated in 2 lbf divisions. Set of six needles alow multiplication to maximum 8000 lbf reading.
Acme penetrometer features cast aluminum base and set of stainless steel Proctor needles in a wooded block (bearing area: 1, 1/2, 1/4, 1/10, 1/20 and 1/40 in2; (645, 323, 161, 65, 32 and 16mm2). Includes 100 laboratory test data reporting forms. Meets ASTM C403; AASHTO T197.
