2021-07-20 09:54

The density of GRC is 1.8~2.0 tons/cubic; the service life is about 50 years; the fire rating is A1; the bending strength is greater than 8~30Mpa; the compressive strength is greater than 40~80Mpa; the water absorption rate is not greater than 14% according to the standard requirements, our products The actual measurement is not more than 9%; the freeze-thaw resistance has passed the test of minus 35 degrees, 50 freeze-thaw cycles, and the product is qualified, which is much better than the standard 25 freeze-thaw cycles; the impact resistance is 10~30 N mm /mm2.
