DYE-300S Integrated Cement Flexural and Compressive Strength Testing Machine
The DYE-300S cement flexural and compressive strength testing machine is primarily used for determining the flexural and compressive strengths of cement mortar. With its compact design and user-friendly operation, it is an ideal piece of equipment for cement plants, construction engineering firms, quality inspection stations, and educational institutions. It is also widely employed for compressive strength testing of materials such as bricks, stones, cement, and concrete, as well as for evaluating the compressive performance of other materials.

Input voltage: 380V
Motor power: 0.75 kW
External dimensions (L×W×H, mm): 1220×500×1250
Host weight: 550 kg
II. Installation of the Testing Machine
The installation foundation for this testing machine shall be solid and reliable. To facilitate operation and ensure accurate readings, the foundation may be raised slightly above ground level, with the height determined according to actual requirements. A clearance of at least 0.7 m shall be maintained around the testing machine to allow for maintenance and operation. Anchor bolts (M12×300 mm) shall be installed using a two‑stage grouting process to ensure proper embedding.
(See the figure for installation basics.)
During installation, the testing machine shall be kept level (levelness ≤ 0.2/1000), and it should be used…
0.1/1000. Use a box-type spirit level to check the flatness of the lower platen. If the horizontal or vertical level deviates from the specified tolerance, adjust it by adding shims beneath the base plate, then tighten the foundation anchor nuts.
Then connect the power cord; this unit shall be equipped with a grounding protection device, and the supply voltage variation shall not exceed ±10% of the rated value.
III. Maintenance and Servicing
1. The testing machine shall be installed in an environment that is clean, dry, with uniform temperature, free from vibration, and protected from corrosive gases.
2. The testing machine shall be kept clean, and its unpainted components should be regularly lubricated to prevent rusting.
3. After six months to one year of operation, the testing machine should have its hydraulic oil changed once. During the oil change, thoroughly clean the oil tank and the oil filter. To clean the tank, pour kerosene into it, flush it out, and repeat this process several times until the tank is completely clean; then wipe the bottom of the tank dry with a towel before adding fresh, clean hydraulic oil. If, during routine use, the hydraulic oil becomes severely cloudy and is no longer suitable for continued operation, it must be replaced immediately; otherwise, wear on various hydraulic components will accelerate, potentially compromising the accuracy of the measured values.
Hydraulic oil specifications are recommended as follows, depending on the ambient temperature:
(1) When the ambient temperature is between 10 and 20°C, use GB-443-84 N46# (equivalent to No. 30 mechanical oil).
(2) When the ambient temperature is between 20 and 30°C, use GB-443-84 N86# (equivalent to No. 40 mechanical oil).
4. When not in use, the machine should be covered with a plastic cover.

Frequently Asked Questions
Is the universal materials testing machine experiencing loading stalling or abnormal zeroing of load data?
1. Loading lag: Clean the lead screw and guide rails, apply lubricant, and remove debris from the transmission components. 2. Zeroing anomaly: Restart the equipment system, calibrate the load and displacement zero points, and check for poor electrical contact in the sensor wiring. 3. Overloading is strictly prohibited; before testing, verify that the grips are securely tightened to prevent eccentric loading of the specimen.
How often should in‑instrument verification be performed? Which instruments are required to undergo it?
High‑precision, high‑frequency‑use, and drift‑prone equipment (such as balances, penetration testers, water permeability testers, and sensor‑type devices) shall undergo intermediate verification every three months; routine equipment shall be verified every six months. Equipment that is within the verification/calibration interval, has been repaired following a malfunction, or has been relocated must undergo additional intermediate verification, with complete verification records maintained.
Is the repeatability of pendulum-type pavement friction coefficient measurements poor?
Key points for resolution: Prior to testing, thoroughly clean the pavement at each measurement point, ensuring there is no standing water, dust, or debris; calibrate the instrument’s level and zero point to ensure a standardized pendulum‑drop trajectory; strictly control the pendulum’s sliding distance; avoid conditions such as strong winds, wet pavement, or abrupt temperature changes; and calculate the average of multiple measurements taken at the same point.
How should one handle cases where the pavement infiltration meter data exceeds allowable error limits, exhibits leakage, or shows abnormal readings?
1. Sealing leaks: Inspect the base seal for aging or damage and replace it promptly; before testing, firmly press down on the base to expel any residual air inside. 2. Data deviation > ±2%: Calibrate the level sensor, clean any fouling from the graduated cylinder, and check for damage to the scale markings. 3. Compliance with new regulations: For seepage rates ≤ 300 mL/min, existing equipment may continue to be used; for rates > 300 mL/min, the accuracy of older equipment fails to meet standards, and such equipment must not be used.
Can the old Marshall compaction apparatus and stability tester still be used?
According to the 2025 revised asphalt testing procedures, after adjusting the indenter configuration on the Marshall stability test apparatus, existing instruments currently in use may continue to be operated normally without mandatory replacement; only periodic calibration to maintain accuracy and ensure equipment integrity is required.
What are the causes of uneven compaction and layered cracking in molded specimens during compaction testing?
Main causes: non‑vertical drop of the compaction hammer, rail jamming, excessive deviation in hammer weight, uneven layer thickness during loading, insufficient number of blows, or overload. Solutions: regularly lubricate the guide rails; verify and correct the vertical alignment of the hammer; strictly follow the procedure for layered material placement and step‑by‑step compaction; ensure that hammer weight and drop height comply with standards; and prevent over‑thick layers.
