Cement Compression Testing Machine 40*40mm Cement Compression Test Fixture

Product Description

Standard: JC/T683,GB/T17671.

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.
