Geopolymer piles would be stronger and more durable than Portland
Geopolymer’s superior strength and performance in comparison to Portland is leading to the development of more and more products. Companies such as BCRC in Australia are exploring numerous possibilities. Please let me know of other companies developing similar products.
“BCRC’s team is at the leading edge of Geopolymer research and is perfectly placed to assist companies wanting to take a lead in the lucrative advanced materials market.
BCRC’s undertake market assessments, provide technical review and assist in developing product and marketing literature for admixtures, additives, repair materials, SCM’s, fibres, cement systems, grouts, mortars, concretes, construction systems & light weight products. BCRC are leaders in Geopolymers and can manage a company’s rapid development of geopolymer products. BCRC combine technical, construction and marketing expertise to assess product development requirements.
Geopolymers were reinvented in the 1970’s but development work has remained of a confidential nature. It has been targeted at specific products for specific companies. Development costs were high but recouped by the mass production in items such as cars. But now development of products is a relatively low cost. Even moderate size companies can afford to become involved.
Sewage pipe: This is an ideal Geopolymer product as factory production will enable accelerated curing to give high throughput and eliminate the cost of pipe liners to protect against Hydrogen Sulphide induced acid attack.
Culverts: Culverts often transmit contaminated water leading to chemical attack. Geopolymers will provide a high degree of protection.
Precast facades: Geopolymers will enable lightweight durable panels to be used to reduce the load on the structure and have a double effect on cost reductions.
Precast Beams & Columns: There is an increasing trend to using precast beams and columns to reduce construction programmes and minimize on site labour. Geopolymers will enable quicker production and reduced member sizes due to the higher load capacities.
Precast Piles: Geopolymers are particularly suited to the use of precast piles in Acid Sulphate Soils, a major issue in NSW and Queensland.”
