Concrete Rock Compression Testing Machine

Product introduction

DYT-100 concrete rock compression testing machine is mainly used to study the mechanical properties of brittle materials such as rock and concrete. The technical indicators comply with the People's Republic of China water conservancy industry standard SL/T264-2020 "Water Conservancy and hydropower Engineering rock test Regulations" and JTG E41-2005 "Highway Engineering Rock Test Regulations". The equipment is the necessary equipment for the laboratory of highway, railway, bridge, building materials, colleges and universities, survey institutes and other industries.

Main functions and characteristics

1. Mainly used for compressive strength detection of concrete and rock specimens;

2.The equipment can measure elastic modulus test, Brazil splitting test, three point bending test;

3. The axial pressure adopts high precision and low speed CNC metering oil source speed control system (patent number: ZL 2015 2 1057375.8), the system can be stable and low speed operation (minimum 0.01mm/min), low energy consumption, no noise;

4. Our company's concrete rock compression testing machine stress loading speed 30KN/min is very fast, a short time can make the sample damage. In order to prevent sudden burst damage of samples caused by rapid loading, our products are designed with automatic control of stress and strain conversion mechanism in the software. Stress loading is used in the initial stage of the test, and when it reaches about 70% of the expected strength, the system automatically converts the stress loading into strain loading (the stress and strain conversion can also be set at any time and any position) to ensure that the whole process parameters of the stress and strain test are obtained in the accurate control measurement. Ensure accurate measurement to the peak and the whole process after the peak, ensure the determination of the complete strength curve, and ensure that the extensometer is not damaged during the measurement control process.

5. The operating system of the machine is controlled by the computer to complete the test, or according to the test method steps designed by the user. Automatically realize the automatic storage of test data, automatic processing of test results, drawing graphs. For users who want to organize the test report in a non-standard form, you can use Microsoft Excel tools to call the raw data in the database file and then process it yourself.

6. Equipped with overload and limit protection, when the loading force exceeds the rated theoretical value, the system automatically unloads and stops the test.
