40mmx40mm cement resist compression fixture

cement resist compression fixture, Compression jig 40X40mm, Cement compressive fixture.

Purpose: the compression testing machine to determine the compressive strength of cement
Standard: JC/T683、GB/T17671.
Technical parameters：
1.Length of upper and lower platens: 40mm
2.Width of upper and lower platens: >40mm
3.Vertical clearance between platens: >45mm

In order to ensure the quality of resist-compression fixture,our country has established the industrial standard for the cement resist-compression fixture JC/T683-2005,which has established strict regulation on the technical requirements of the cement resist-compression fixture. According to the regulation,our company has made efforts to improve and research for two years,and cooperated with physical room of national building material institution.Our company has finally developed the resist-compression fixture to measure to strength of the cement mortar which is in accordance with industrial standard of JC/T683-2005 and suitable for the measuring method for the strength of cement mortar in GB/T17671-1999.
Technical parameters:

1. he width of upper and down clamp: 40mm±0.1mm
2. The flatness in the surface of upper and down clamp: 0.01mm
3. The rigidity of upper clamp,down clamp and compression leg: 60HRC
4. The contact ratio in the long direction of upper clamp and down clamp: ≤0.2mm
5. The free distance of upper clamp and down clam is more than 45mm
