CEMCOTEC offers manufacturers or specifiers independent mechanical property testing of GRC [GFRC] to the GRCA’s “Method of Testing GRC Material Part 3 – Determination of Flexural Properties” which measures LOP (Limits of Proportionality), MOR ( Modulus of Rupture), Strain to Failure and Youngs Modulus. Testing to EN1170 part 5 can also be carried out. The data can be used for confirmation of the GRCA’s Grade 8, 10 or 18 GRC by the manufacturer or their clients. A full interpretation of the results can be given. Briefly, the test involves bending a 10-12mm thick x 275mm long x 50mm wide coupon of GRC cut from a test board made at the same time as production panels and then measuring and recording the above properties.
“After normal factory quality control, these tests essentially confirm the quality of the GRC being put into use”
Testing is carried out on a UKAS Certified Testometric M350-5CT Universal testing machine
Full quality control advice can also be given including assistance in setting up quality assurance systems.
