| The
properties of Glass fibre Reinforced Concrete (GRC) vary according
to the production method, mix design, and the type and content of
the alkali resistant Glass fibre.
Traditional
Spray can produce the highest strengths due to a high AR Glass fibre
content, low water/cement ratio, long fibre length and planar fibre
orientation.
Premix
Strengths are generally lower than those of the Traditional Spray
method due to lower AR Glass fibre reinforcement contents, higher
water/cement ratios, shorter fibre lengths and 3-dimensional fibre
orientation.
Sprayed
Premix gives consistent mechanical properties similar or higher
than those obtained with vibration cast premix.
