 WHAT IS GRC ?

GRC stands for Glass Fibre Cement Renforced. In America they call it  GFRC, in Europe and Japan they call it GRC. GRC is a kind of concrete with high quality and can be made thinner panels and installation of Glass Fiber Reinforced Concrete. GRC forms can be made thinner because without the use of a split, and using Fiber glass as its reinforcement. Although the high quality, but more GRC in use as a material that is both architecturally.
 
HISTORY OF GRC

  1.  1960: End of 1960 alkali resistant fiber development has been successfully implemented in  the  United States.
  2.  1968: Dr.Majumdar of Building Research & Establishment, UK has investigated AR Fiber familiar with the content of ZrO2.
  3. 1970: Chinese Building Material Academy also successfully developed AR Fiber
  4. 1973: AR Fiber commercially manufactured by Pilkington (UK) with the product name CemFil.
  5. 1975: In the American system developed steel stud framework for GRC panel.
  6.  1976: Japan's Nippon Electric Glass Fiber AR commenced production with a higher content of ZrO2.
  7. 1978: GRC products into Indonesia and the first building to use the GRC is building  Widjojo Center in jl.jend.Sudirman Jakarta.
  8. 1985: Chi Chibu Cement, Low Alkali Cement Japan developed.
