Product description
GRC products are mainly performance and technical parameters
一、mechanics

1. Tensile strength: (glass fiber reinforced concrete) tensile early-4.0 to 5.0 MPa.
2. Compressive strength: not enhanced with cement mortar little changed compared to, or even lower, but lower rate of not more than 10%. 
3. Toughness: glass fiber reinforced concrete in the flexural deformation when a larger capacity, it toughness high, bending at the destruction of their toughness than enhanced mortar increase 30 to 120 times. 
4. Impact strength: Pendulum measured by the glass fiber concrete impact strength for 15 ~ 30 Kg/m2
5. Shells will die: and not enhanced compared to a slight increase of cement mortar, and its value is (2.6 ~ 3.1) × 104Mpa.

二、the physical properties

1. The density and water absorption: density of 1.9 ~ 2.1 g/cm3, water absorption was 10% to 15%. 
2. Antifreeze: Antifreeze by concrete experiment, at minus 10 degrees Celsius, 15 times repeated freeze-thaw cycle test, no stratification and cracking phenomenon occurred.
3. Heat resistance: its use of the temperature is not more than 80 degrees Celsius. 
4. Impermeability: not only is not high water permeability, in humid conditions, there is also a higher gas-tight sexual.
