The following problems can be solved:
Simulate the real environment: The sulfate dry-wet cycle test can simulate the actual use conditions of concrete in sulfate environments such as saline-alkali land and coastal areas, providing a scientific basis for engineering design and material selection.
Improve durability: Evaluating the sulfate erosion resistance of concrete through testing helps to optimize the concrete mix ratio, extend the service life of the structure and reduce maintenance costs.
Ensure engineering safety: In sulfate environments, concrete is prone to corrosion and spalling, which seriously affects structural safety. By discovering problems in advance through experiments, engineering hazards can be effectively avoided.
Promote technological progress: Provide data support for the development of new concrete materials and new processes, and promote technological progress and innovation in the industry.
Application scenarios include:
Scientific research institutions: used for concrete durability research, new material development and corrosion mechanism analysis.
Engineering quality testing center: Evaluate the anti-corrosion performance of concrete structures in sulfate environments to ensure engineering safety.
