Pozza post

High strength precast geopolymer concrete using formulated blend of cementitious materials and locally sourced aggregates.

Pozza post size dimensions are 70 x 90 x 1830mm and weigh 25kg.

Fence wires may be fixed to the post at any spacing by predrilling a hole with impact drill and using self tapping concrete screws (e.g. TX-Con, Tapcon or Grabcon) in combination with clips such as panel clips, U clips, Davo's fencing clip, Vini Clip, Gaffer Staple or similar.

Geopolymer Concrete

The current contribution of green house gas emission from Portland cement production is about 1.5 billion tonnes annually or about 7% of the total greenhouse gas emissions to the earth’s atmosphere. 

Geopolymer cement is a binding system that is a more environmentally sustainable alternative to conventional Portland cement. It relies on minimally processed natural materials and/or industrial byproducts known as pozzolons to significantly reduce the carbon footprint of cement production, while also being highly resistant to many common concrete durability issues.  Pozzolon based concrete is strong, durable and long lasting while only having a small fraction of the carbon footprint compared to ordinary portland cement based concrete.

GRFP

Pozza posts are reinforced with glass fibre reinforcement bar (GFRP) which is a composite of fibreglass and resin. It is impervious to corrosion and a proven alternative to steel for concrete structures requiring strengthening and long service life. It extends concrete durability exposed to salts, saline water, alkali, rust, acids and corrosive enviornments. GRFP rebar has the same thermal coefficient of expansion as concrete which assists with the concrete preformance and durability.

GFRP reinforcement bar offers superior performance compared to traditional steel rebar. With approximately twice the tensile strength and just a quarter of the weight, GFRP provides a high-strength, lightweight solution for concrete reinforcement. GFRP is corrosion-resistant, eliminating rust-related concrete damage, and has a significantly lower carbon footprint than steel, making it an environmentally friendly choice for fence post reinforcement.
