Abstract
The HST YAW2000D is a 2000kN computer control compression testing machine for cement, mortar, brick, concrete and other building materials: servo motor acceleration and deceleration control, electric ball screw test space adjustment, computer auto control of the loading process, and the YAW-D-II Windows test software that shows the load value, loading speed and loading curve while the test data is automatically processed, stored and printed. It compresses concrete cubes of 100, 150 and 200mm and more, rectangular prisms of 400 x 200 x 200mm and 400 x 200 x 400mm, and cylinders from Ø100 x 200mm up to Ø200 x 400mm on the 3000kN sibling, with a test class of 1, load accuracy of ±1.0% over 4-100% F.S and a load resolution of 1/300000 F.S. The series is conformed to test methods including EN 12390-3, EN 12390-4, BS 1881, ASTM C139, ASTM C1231 and AASHTO T22, with force measurement per ISO 7500-1, ASTM E4, EN 10002-2, BS 1610 and DIN 51220. It is the ideal test equipment for quality control at industry and mineral enterprises, education in high schools and technology research at scientific institutes.

What the YAW2000D is for
The machine tests the mechanical properties of cement, mortar, brick, concrete and other building materials. It is mainly designed for the compression test of building material items - concrete cube, concrete blocks, cement specimen and bricks - and it is also used for the compression performance test of rubber pad and the top forge test of metal.
- The loading follows the specimen: servo motor acceleration and deceleration control keeps the load rising at the set rate, and the load value, loading speed and loading curve are shown on the screen during the run.
- The test data is automatically processed, stored and printed, so a full cube batch runs without hand-entered numbers.
- It is the ideal test equipment for quality control at industry and mineral enterprises, education in high schools, and technology researches at scientific institutes.
For a concrete plant laboratory, a cement quality line or a masonry inspection room, this is the standard Concrete compression test machine duty - cubes, prisms and cylinders, batch after batch.
How a compression run is controlled
- The control method is computer auto control of the loading process: the YAW-D-II software drives the run and watches every value behind it.
- Loading uses servo motor acceleration and deceleration control, with a high performance low noise plunger pump, a three-phase asynchronous motor and the high precision electro-hydraulic proportional servo valve with valve block group behind the force.
- The test space is adjusted by electric ball screw, so the operator sets the space for the specimen size instead of hand-winding a lead screw.
- The high precision pressure sensor reads the force: load measuring range 4-100% of F.S, resolution of test power 1/300000 F.S, load accuracy ±1.0%, at a test class of 1.
- Displacement is measured at 0.01mm with an accuracy of ≤±0.5%.
- The screen shows the load value, the loading speed and the loading curve; the data is automatically processed, stored and printed afterwards.
2000kN or 3000kN: choosing between the YAW2000D and YAW3000D
The sheet lists the two frame sizes of the series side by side; the choice follows the largest specimen the lab actually runs:
- YAW2000D: 2000kN max. load, 220 x 250mm upper and lower Compression Platens, 320mm compression test space, 280mm between the columns, Ø250mm piston, mainframe 950 x 350 x 1300mm, about 650kg.
- YAW3000D: 3000kN max. load, 300 x 300mm platens, 400mm compression test space, 300mm between the columns, Ø300mm piston, mainframe 1000 x 500 x 1450mm, about 1000kg.
- Both share the 50mm piston stroke, the electric ball screw space adjustment, the computer auto control, the test class of 1, the ±1.0% load accuracy and the 0.75kW, AC 380V±10% power supply.
- A 200mm concrete cube sits comfortably in the 320mm space of the YAW2000D. A 400 x 200 x 400mm prism or a Ø200 x 400mm cylinder is 400mm tall, which is the territory of the YAW3000D's 400mm space.
- The sheet also notes that the test space can be customized according to the specified specimen size, beyond the standard 320mm and 400mm.

Selection guide: where the YAW2000D fits
- Your program is concrete cubes of 100, 150 and 200mm, or 400 x 200 x 200mm prisms, on a 320mm compression space - the YAW2000D is the frame for that batch size.
- Your program includes 400mm-tall specimens (400 x 200 x 400mm prisms, Ø200 x 400mm cylinders) or higher-strength concrete - step up to the YAW3000D, or ask for a customized test space.
- Your material is cement or mortar: the YAW2000D is the Cement compression test machine for those specimens, with AASHTO T22 among the methods the series is conformed to.
- Your lab also tests bricks, rubber pads or runs the top forge test of metal on the same machine - the compression grip and the 4-100% F.S range cover that side of the work.
- In the HST catalog, this machine sits in the Compression Testing machine family; if your lab also runs general-purpose tensile work on the same samples, the Material Tensile Compression Tester is the wider sibling.
Total cost of ownership
- Power is 0.75kW at AC 380V±10% - an ordinary three-phase industrial circuit, and the three-phase asynchronous motor plus the low noise plunger pump keep the running quiet.
- The 950 x 350 x 1300mm mainframe at about 650kg is a floor-standing unit; the one-piece oil source control cabinet keeps the hydraulics in a single guarded enclosure next to the frame.
- The precision oil filter is in the standard package, so the hydraulic side starts with its filtration already fitted.
- The computer and the HPA4 printer are standard, so no separate report station is needed for the batch results.
