LR-HD concrete single-sided salt-freeze test machine is a high-precision experimental equipment designed for evaluating the durability of concrete in salt-freeze environments. It simulates the single-sided freeze-thaw cycle of concrete under salt-freeze conditions to accurately determine its antifreeze performance, and is widely used in building materials research, engineering quality inspection and other fields.
Core use
Concrete antifreeze performance test: evaluate the durability of concrete in salt-freeze environments and determine its antifreeze grade.
Material performance optimization: optimize concrete mix ratio through experimental data to improve material antifreeze performance.
Engineering quality inspection: used for quality inspection of engineering concrete to ensure that it meets design and use requirements.
Implementation standards
"Standard for test methods for long-term performance and durability of ordinary concrete" GB/T 50082-2024
"Concrete antifreeze test equipment" JG/T243-2009
"Provisional technical conditions for cement emulsified asphalt mortar for CRTSII type slab ballastless track on passenger dedicated line railway"
1. Accurate simulation of salt freezing environment
Using single-sided freeze-thaw technology to simulate the salt freezing conditions of concrete in actual use.
Supports custom settings for salt solution concentration to meet different experimental needs.
2. Intelligent control system
Equipped with a 7-inch color touch screen, the operation interface is intuitive and friendly.
Built-in self-developed software, supports programmed operation and data recording.
Real-time display of parameters such as temperature and freeze-thaw times, automatic storage of experimental data, and support for historical data query.
3. Efficient experimental capabilities
Single freeze-thaw cycle time is short and experimental efficiency is high.
Supports simultaneous testing of multiple groups of specimens to meet the needs of large-scale experiments.
4. Safe and reliable
Equipped with high and low temperature protection function to prevent the equipment from being overcooled or overheated.
After the test is accidentally interrupted, the equipment can automatically resume operation to ensure the continuity of the experiment.
Multiple alarm functions, real-time monitoring of the equipment operation status, to ensure experimental safety.
5. Energy saving and environmental protection
Adopting an efficient refrigeration system, low energy consumption, and operating cost savings.
Optimized equipment structure, reduced salt solution consumption, and reduced experimental costs
