What is the standard value of GRC durability?
The durability of the GRC standard value is actually not a strict labeling, usually measured in life, in the last century in 90s generally can be used for 20 years, and now can be used for 50 years, a few can be used for 70 years, 70 years it can be said with the same building life.
Truly qualified GRC products and its durability is almost the same concrete (generally 50 years), but the domestic nine out of ten GRC are only a few years of life, especially inside the reinforced GRC, think of the strength of the mortar is much clear that the quality of life and what is the fake GRC. Only the alkali resistant fiber (of which two zirconia content is an important index to more than 16%) the content of not less than 4.5% is qualified, and its production process and standard, to dense.
GRC is the abbreviation of English Glass fiber Reinforced Concrete, and the Chinese name is glass fiber reinforced cement. GRC is a kind of fiber cement composite material with alkali resisting glass fiber as reinforcing material and cement mortar as base material. GRC is a kind of material that expresses designer's imagination through shape, texture, texture and color
The durability of truly qualified GRC products is almost the same as that of concrete (usually 50 years).
