This equipment is suitable for determining the frost resistance of concrete specimens under conditions of freezing and thawing in water, represented by the number of rapid freeze-thaw cycles they can withstand. The HNJ-DR-28E Rapid Freeze-Thaw Test Chamber for Concrete has been confirmed its high reliability by long-term user experience. It provides an important quality assurance for the testing of long-term performance and durability of concrete, meeting the needs of research institutes, colleges and universities, design, construction, quality inspection and other departments in related industries for rapid freeze-thaw testing of concrete.
This equipment is applicable for determining the frost resistance of concrete specimens under atmospheric conditions and in contact with salt, which can be represented by the number of freeze-thaw cycles they can withstand, the mass of surface spalling, or the relative dynamic modulus of elasticity measured by ultrasonic methods.
This testing instrument is designed for user-friendly operation and features automated testing once parameters are set, making it an ideal choice for evaluating the resistance of concrete specimens to sulfate attack.
Hot Deformation Vicat Softening Point Tester is mainly used for measuring the thermal deformation temperature and Vicat softening point temperature of non-metallic materials. This instrument is easy to operate and has precise control, and is widely used in colleges, research institutions, and product quality supervision and inspection units.
The notched prototype is a standard notched spline used for impact testing of non-metallic materials such as plastic and organic glass using mechanical processing methods.
