Purpose
SYQ61 concrete strength tester is used to test compressive strength of concrete by two ways: rebound and ultrasonic-rebound method. Also, it can be used to test sound time and speed in concrete.
Specification
Technical specification for inspection of concrete compressive strength by rebound method (JGJ/T23-2011)
Technical specification for detecting strength of concrete by ultrasonic-rebound combine method (CECS02:2005)
Performance
1. Multi-function for testing compressive strength of concrete. It is used to test the compressive strength of concrete by rebound method and ultrasonic-rebound method.
2. Get the compressive strength value of concrete by ultrasonic-rebound method in one instrument. It need two instruments usually, one to test sound speed in concrete, the other to test rebound value.
3. Can save test date. This is convenient for laborer data management.
4. Real USB transmission. Data can be transmitted to computer for future process and analysis.
5. Powerful data process and analysis software in windows. Test data can be export to word or excel for future process and analysis.

According to: Technique Regulation of Concrete Defect Detection with Ultrasonic CECS21: 2000 Depth measurement principle When vibration energy transmits through the concrete and passes the crack, the vibrate energy will be diffracted at the point of the crack, whose diffraction angle has geometrical relationship with the crack depth. DJCS-05 crack depth measurement instrument adopts this geometrical between the diffraction angle and depth to realize high precision depth measurement. Feature and Specification Easily operation: Start measure when turn on, simply press to finish testing. Result Intuition: No wave speed test and calculate to display the crack depth directly Data processing: Data can transfer to PC, and then generate test report rapidly. Depth scale: 10-350mm Test precision: 5% Data storage: 10600 depth data Display: 4” Resolution 160*128 Power supply: 9VDC (6 AA battery) Work environment: Temperature -5~40centigrade; Humidity 85% Size: 220*180*80mm Weight: 1000g

1. Size of concrete specimens for compression strength test Concrete cubic specimen: 150X150X150mm, 100X100X100mm, 200X200X200mm Cylindrical concrete specimen: diameter 150X300mm, diameter 100X200mm, diameter 200X400mm 2. Brief introduction of concrete compressive strength test procedure 1) Placing the concrete specimen---place the test specimen on the lower bearing block. Carefully align the axis of the specimen with the center of thrust of the spherically seated block. 2) Apply the load continuously and without shock until the specimen fails and record the maximum load carried by the concrete specimen during the test. Note the type of failure and the appearance of the concrete. 3.Relative test method GB/T 50081 standard for test method of mechanical properties on ordinary concrete ASTM C39 standard test method for compressive strength of cylindrical concrete ASTM E74 practice of calibration of force-measuring instruments for verifying the force indication of testing machine 4.

200 tones in different models. Portable models are very convenient and useful for site use where carrying frequently the specimens for testing in a standard laboratory is inconvenient and uneconomical. With special attachments, the machines can also be used for bricks, hallow or solid concrete blocks, using appropriate capacity machine. In general compression testing machine consists of a load frame with suitable platens and a pumping unit with pressure gauge, either hand operated or electrically-cum-hand operated. Load frame and pumping unit are connected by pressure pipes. Wooden packing
