The soil hydrometer jar measures suspended solids in sedimentation cylinders over time periods of 24 hours. Soil specimens mix in a solution of water and sodium hexametaphosphate. The hydrometer bath provides a 68°F ambient temperature throughout the unit. Using a microprocessor-based temperature control with integral heater and chiller. In addition, the bath comes fully insulated and has a capacity of 8 hydrometer jars.
Liquid LimitThe liquid limit set performs Atterberg or liquid limit tests in accordance with ASTM specifications. It determines the water content at which soil changes from a liquid to a plastic state. A soil sample placed into a cup in the machine separates into two halves using a grooving tool. The crank on the machine rotates so that the cup holding the sample strikes the base of the test machines. Machines are available with counters and motors if preferred. The soil grinder quickly prepares dry soils samples for limit tests, particle size analysis and other standard lab tests. It preserves true grain size for accurate and repeatable test results. The resiliency tester measures resiliency of the hard rubber base of the liquid limit machines. Complete tests within a 90 day interval to ensure the base meets ASTM D4318 standards.
Plastic-Shrinkage LimitPlastic-shrinkage limit testing equipment for all plastic and shrinkage water content needs. Plastic limit measures water content when a soil can no longer be rolled into 1/8″ diameter threads without crumbling. Plastic limit subtracts from liquid limit to establish the plasticity index. The plastic limit test includes all components to perform the plastic limit test in accordance with ASTM and AASHTO standards. Shrinkage limit measures water content where further loss of moisture does not cause a decrease in volume of a specimen. Samples for shrinkage limit tests usually take from a larger sample prepared for liquid and plastic limit tests.
Relative DensityRelative density testing works best when granular soils do not respond well to Proctor moisture-density tests. Determine maximum density by placing soil sample in molds and densifying using a vibrating table and surcharge. Determine minimum index density by loose placement in the molds using pouring funnels, scoop, or shovel, of soil particles. The vibrating table has a cushioned steel 30″ x 30″ deck. It activates by an electromagnetic vibrator with over a 100lb actuator. The solid state circuitry allows precise amplitude control even with fluctuating voltage supplies. The relative density molds are constant volume change cylinders that regulate sample size in determining relative density of cohesionless soils. The gauge set fits guide brackets of either mold set to measure distance. Measuring from the top of the mold to the top of the base plate after densification.
Sample EjectorsSample ejectors quickly extrude compacted soil or asphalt samples from soil density or Marshall compaction molds. The sample ejector works for both lab and field use to extract soil samples from 4″ and 6″ compaction molds. The ejection force generates by means of a 3-ton capacity, hand operated hydraulic jack. The cast-aluminum ejector head assembly positions at different heights through the use of quick release pins. This helps the operator to easily match the ejection travel to the height of the mold being used. In addition, adapter ring accessories provide soil samples from 2″, 2.5″, and 3″ diameter Shelby tubes to be extruded.
Sand EquivalentThe sand equivalent test indicates the relative proportions of clay-like fines in granular soils and aggregates. The manual shaker works best for use on the job site to give more uniform shaking action. Uniform shaking action pushes the top frame by a simple stroke of the hand. The portable unit features a removable wooden case. As well as two separate electronic timers to increase accuracy and ease of operation compared to a spring-type timer. The consistent, repeatable oscillation of the apparatus eliminates operator-cause variation. Sand equivalent stock solution works with distilled water in the ratio of 85ml solution per gallon of water. Made from anhydrous calcium chloride, glycerine, and formaldehyde.
Triaxial/PermeabilityTriaxial/Permeability soil testing equipment provides information about shear resistance and strength. As well as cohesion to predict slope stability and structural foundation behavior.
Dispersion ApparatusDesigned for the Pinhole Test, the Pinhole Dispersion Apparatus identifies the dispersive characteristics of soil. As well as, helps determine the stability of clay soils used.
De-Airing TanksDe-airing tanks produce batches of de-aired water without the use of heat. Designed to remove dissolved gasses from ordinary tap water. In addition the de-airing system can de-air water to less than 0.5 pph dissolved oxygen in 4 minutes.
Control PanelsControl panels feature longer burettes and 0.02ml graduation that give more accurate results and faster turnaround time. The flex panels feature single cell, double cell and master control panels. These panels include a digital readout pressure meter, pressure supply gauge. As well as a master pressure regulator. The add-on logic panel provide additional triaxial and permeability test chambers. This helps to increase the economical productivity. In addition, these panels attach to the Master Logic Control panel. By using the master’s digital pressure readout they display the confining cell pressures. The design of the master logic control panel combines precise control, logic layout and quality components for accuracy.
Load CellsLoad cells measure in either compression or tension to an accuracy of less than 0.0300% strain. Constructed out of stainless or nickel alloy plated steel.
Load FramesLoad frames work with CBR, UCC, UU, soil cement and Marshall testing. Load frames feature RS232, high speed platen advances, and mechanical jacks to provide steady test speeds.
Load RingsLoad rings measure compression with their high strength aluminum alloy. As well as their repeatable elastic deformation ability under varying loads.
PermeametersPermeameters test granular samples using either the constant-head or falling-head methods. Constant and falling head use the permeameter, manometer tube, two funnels and either porous stones or perforated screens. Other permeameters like the Shelby tube test undisturbed soil samples in sections of 3 in diameter Shelby tubes. Consisting of corrosion-resistant top and bottom plates, valves and two porous stones. Another permeameter such as the Compaction permeameter determines the permeability of clay, sand and gravel. Molds come with upper and lower plates that feature inlet/outlet connectors for water to flow through.
Test ChambersTriaxial test chambers feature a precision ground and polished stainless steel load piston designed for low breakaway friction. In addition, they also work as flexible wall permeability testing applications.
Testing AccessoriesAll of the testing accessories you could need for a triaxial or permeability test. Accessories available range from, open end wire saw, latex membranes, o-rings, and high vacuum grease. In addition other accessories include 2 part compaction molds, 2 part miter boxes and vacuum split molds.
