5. Long Term Durability
• Forton increases the
strain to failure at 28
days
• Field tests show that
high strain to failure is
only maintained with
Forton

6. Long Term Durability
Aged 16 year w/o Forton
Aged 16 year w/ Forton
w/o Forton -- brittle break, straight break line, few fibers
w/ Forton -- ductile break, jagged break line, abundant fibers

7. Face Cracking
The use of 6% Forton
eliminated face cracks in
panels that consistently
cracked without.

: THE time tested material for GFRC

9. Summary
• The foundation for quality GFRC
– designed specifically for GFRC
– manufactured to tight specifications
• Consistently produces desired results
• Produces GFRC with maximum 28 day strength
w/o 7 day wet cure
• Produces more water resistant GFRC with lower
water absorption compared to SBR latexes
• Prevents face cracking
• Produces highly ductile GFRC that remains ductile
for decades
• The time tested material for GFRC
