Concrete Unilateral Salt Freeze-Thaw Testing Machine Concrete Frost Resistance Tester Concrete Long-term Performance Test Device
Concrete Unilateral Salt Freeze-Thaw Testing Machine Concrete Frost Resistance Tester Concrete Long-term Performance Test Device
Product Introduction
The freeze-thaw testing mechanism of our company's Concrete Unilateral Salt Freeze-Thaw Testing Machine is designed in accordance with RILEM recommendations. This machine is used to determine the frost resistance of concrete when subjected to freeze-thaw cycles within an atmospheric environment, as well as when in contact with salts or other corrosive media. Durability is a critical indicator directly related to the strength of concrete.
This product complies with the requirements of GB/T 50082-2024 Standard for Test Methods of Long-term Performance and Durability of Ordinary Concrete and JG/T 243-2009 Concrete Frost Resistance Testing Equipment*.
Based on the prescribed testing procedure, the Concrete Unilateral Salt Freeze-Thaw Testing Machine enables the determination of the degree of surface deterioration (weathering) and the unilateral frost resistance of concrete specimens through multiple freeze-thaw cycles.
Key Features
Our Concrete Unilateral Salt Freeze-Thaw Testing Machine features an integrated, all-in-one design. It boasts a well-engineered exterior structure, while the inner chamber is constructed from 304 stainless steel to ensure effective corrosion resistance. The equipment occupies a minimal footprint, requires no complex installation, and is easily transportable. The refrigeration system utilizes an air-cooled unit, offering excellent heat dissipation and high energy efficiency. The compressor—a world-renowned brand (Danfoss)—delivers high energy efficiency and stable performance. Temperature heating and cooling are controlled via an adaptive PID algorithm, ensuring high-precision temperature regulation. High-precision Pt100 sensors are employed to significantly enhance overall control accuracy.
Application Fields
This equipment is utilized for the unilateral durability testing of concrete in various engineering projects—including marine structures, hydraulic works, bridges, tunnels, and industrial and civil buildings. It is an essential piece of equipment for concrete durability laboratories within research institutions and academic organizations.7Concrete Unilateral Salt Freeze-Thaw Testing Machine Concrete Frost Resistance Tester Concrete Long-term Performance Test Device
