Humboldt USA
Air entrainment meter 8 litter
Concrete Air Meters measure the air content of fresh concrete in accordance with DIN EN 12350-7, ASTM C231, GOST 10181 standards test methods. Humboldt offers a selection of air meters for use in testing fresh concrete specimens or concrete mixes, lightweight aggregate concrete, or other lightweight mixes.
Aggregate Testing Equipment
Soil Mechanics Testing Equipment
Soil Consolidation System HM-5470.3F ConMatic IPC is a fully-automated, incremental pressure controller for performing incremental consolidation tests. The ConMatic IPC allows consolidation, constant load and volume swell tests to be run automatically, freeing up technicians for other tasks and reducing the duration of the testing procedures by more than half—effectively saving time and manpower and increasing lab profitability.
One ConMatic IPC automated system can replace the production of several manual machines—running incremental consolidation tests according to ASTM D2435 Method B, where successive load increments are applied after 100% primary consolidation.
Automatic Mechanical Compactor
standards: ASTM D1557, ASTM D1883, ASTM D5102, ASTM D558, ASTM D560, ASTM D698, ASTM 5102, ASTM D559, AASHTO T99, AASHTO T134, AASHTO T135, AASHTO T180
The mechanical compactor automatically compacts and rotates mold after each blow while keeping track of the number of hammer blows and shutting off once a preset number of blows is reached. The start/stop function of the compactor is independent of the counter. The unit can be used to perform standard or modified compaction tests using a 5.5 lb. (2.5kg) hammer with 12″ (305mm) height of drop or a 10 lb. (4.5kg) hammer with 18″ (457mm) drop. Hammer lift compensates the height of the drop for soil thickness in the mold during compaction. Hammer weight is concentrated at the foot, allowing free fall of the hammer. Hammer changes are made from the front side of the compactor, making maintenance/adjustments easier without moving machine away from mounted location.
Cement Testing Equipment
Supports the following standards: ASTM C109, ASTM C185, ASTM C230, ASTM C452, ASTM C87, AASHTO T71, AASHTO T106, AASHTO T137 AND AASHTO T152
Used to determine the flow of hydraulic cement, mortars, and cement pastes. A test specimen is molded on the table to a specified volume and shape. Then, with the mold removed, leaving the test specimen on the table.
The table is dropped and raised (via a hand crank or optional motor) a specified number of cycles, after which the flow (or increase in average diameter of the specimen) is measured. Motorized flow table with 10″ (254mm) dia. cast-bronze table/platen and automatic digital counter. Motor stops automatically once pre-set number of drops is achieved. Includes heavy-duty table/platen assembly, standard
Asphalt Testing Equipment
Marshall Compactor, Auto, Rotating Mold Configuration, Heavy Duty
Supports the following standards: AASHTO T245, AASHTO PTM705Humboldt automatic, Marshall compaction machines are designed to provide a stable and rigid mechanism for producing 4″ or 6″ diameter asphalt pills used in Marshall tests.
These Marshall compaction machines are available in two types of configurations: one with a rotating mold with a tapered-foot hammer assembly, and the other, a stationary mold with a flat-foot hammer. Both models feature a heavy-duty design, which stands up well to the constant jarring caused by the compaction process.
