LSY-22 Split-Type Rapid Freeze-Thaw Testing Machine for 16 Concrete Specimens

Description

Product Introduction:

The testing procedures for hydraulic concrete, as specified in SL/T 352; the standard test methods for long-term performance and durability of ordinary concrete, outlined in GB/T 50082; and the standard test method for rapid freeze–thaw resistance of concrete, defined in ASTM/C666—this testing machine is also designed to meet the test conditions stipulated in the JTJ 53-94 standard. Additionally, it can perform low‑temperature tests down to –40°C or lower, as required by the user. Operating principle: the water freeze–thaw cycle method.

Test Objective:

1. The experiment confirms the frost resistance grade of concrete.

2. Calculate and verify the concrete’s durability coefficient.
