BC-450 Series Basic Concrete Compression Machines are manually operated and perform complete strength tests for a variety of concrete sample types, including cylinders, beams, cubes, cores, and grout prisms. A versatile and cost-effective option, these models are ideal for many concrete strength test applications.
Units have a durable, welded steel frame with solid crossheads. This design exceeds ACI 363 requirements for system rigidity. The integrated electric motor and hydraulic pump system operates at variable speeds to achieve and maintain the pressure required for the test. This energy-efficient configuration reduces heat buildup and extends the service life of the hydraulic components.
With the advanced Windows-based human-machine interface (HMI) controller, the operator can select the test protocol, view data, and print or transfer data after test completion. During testing, force, stress, and rate of load are displayed, as well as real-time graphing of load vs time or stress vs time. The controller is used for setup, calibration, and diagnostic functions.
Basic Compression Machines are compatible with the Gilson Guardian Cloud Sharing Application, purchased separately, which enables cloud storage and data management. Seamlessly communicate project information and retain detailed testing data for every test.
The operator controls the load operation in order to perform a test. To do this, initial loading is performed using full advance of the four-position lever valve to seat the cylinder and quickly apply the preload of less than half the cylinder’s expected compressive strength. Then, the operator manually switches the valve lever to the metered position for control and adjustment to the load rate. When the load applied drops below the preset percentage of the peak load, the controller records the maximum compressive strength.
Safety is enhanced with a hydraulic safety relief valve that prevents loading beyond machine capacity and a travel limit switch that stops the piston from advancing beyond limits. Clear Lexan™ hinged fragment doors latch securely while still permitting the operator to view the sample during testing.
Units are supplied ready for compression testing of 6x12in (152.4x304.8mm) concrete cylinders with user-supplied unbonded neoprene capping pads and steel retainers. Accessories are available to adapt the frame for additional testing of cylinder sizes, beams, cubes, cores, or grout prisms. Units operate on 110V, 60Hz. Add “F” suffix to the model number for 220V, 50/60Hz operation.
