Humboldt -Testing Equipment for Construction Materials
The Phunque Flask is the key element in a newly developed method for conducting specific gravity/absorption determinations for aggregate. This method has been designed to eliminate the inherent guess work built into ASTM C128 and AASHTO T-84— the current cone and tamper methods in use today. The test is easy to perform, easy to understand and easily reproduceable between technicians and labs; and is very easy to run reliably in the field. The test can be especially helpful in asphalt operations where specific gravities can make a big impact on pay factors. This test lets the contractor check specific gravities on the material he is currently using, and not rely on lab tests, which may not be current.
The test provides repeatable and consistent test results despite the use of different labs or technicians. It also enables the contractor and DOTs to begin to come to terms with the inherent problem of how much the aggregate from a given pit or source varies, both by location within the pit, and from different fundamental geological characteristics.

Non-destructive strength testing of concrete has a whole new look thanks to the new Silver Schmidt Test Hammer. The new Silver Schmidt redefines strength testing with the use of what is called a "Q" value as opposed to the classic use of an "R" value. What this means for you is that the new Silver Schmidt provides a more accurate method of measuring impact and rebound, which eliminates the need for referencing a chart, based on orientation, to determine the strength of concrete. The new Silver Schmidt calculates the test results and provides the concrete strength in any of the many user-defined measurement modes.
The Silver Schmidt provides an easy-to-use graphical, icon interface that provides the operator complete control of the test parameters and results display. The new hammer can be attached to a computer for downloading of test information. Review of test data can also be performed with the unit itself for the last 20 measurements.
The ConMatic IPC is a fully-automated, incremental pressure controller for performing incremental consolidation and one-dimensional swell tests. The ConMatic IPC allows consolidation and 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 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.
Once a sample has been placed onto the test platform and the test conditions set, the ConMatic IPC, used in conjunction with a computer and Humboldt’s HMTS software, performs all consolidation tests, including moving to the next stress level, without operator assistance. The system automatically moves through the different test parameters specified by the user with incremental consolidation tests typically being completed in 24 to 48 hours.
The unique design of the ConMatic IPC system enables the user to choose from multiple tests and run them independently and simultaneously.

The HM-4152A Distribution Panel is designed to provide all the necessary port connections in one panel for fully automated Triaxial testing. It provides distribution of de-aired water, tap water, pressure and vacuum within the Triaxial testing system for up to 3 Triaxial cells, 1 de-airing tank, 3 cell/back pressure controllers, and 6 air/water bladder cylinders. The panel also houses a pressure regulator, digital pressure readout, air/water filter for the input pressure and de-aired water tank control valves.
The HM-4156A panel utilizes the HM-4152A distribution panel and adds an integral control panel, which allows you to set and monitor cell and back pressure for each of the possible three triaxial cells.
The Pressure Control/Distribution Panel offers a simple and efficient method of monitoring up to 6 independent pressures. The panel controls the distribution of the confining and back pressure supplies to up to 3 triaxial cells by way of pressure regulators and digital pressure readout. In addition the panel offers an air/water filter for the input pressure and de-aired water tank control valves.
