GEOPOLYMER MATERIALS & TECHNOLOGY
Gemite® Group has been developing and manufacturing advanced specialty materials for structural restoration, waterproofing and lining of water, wastewater and infrastructure since 1980’s. Gemite® Materials and Systems have been field tested and verified to extend life span of deteriorated structures to over 50 years.
Geopolymers deliver better physical performance than traditional Portland concrete and provide additional advantages, even in extreme environments, while significantly reducing greenhouse emissions.
Geopolymers offer superior chemical resistance to corrosion, acid and alkali attack, deliver high resistance to temperature and fire, and are better suited in most exposure conditions in various industrial markets, including power production, chemical industry, and oil and gas.
TECHNOLOGICAL BREAKTHROUGH
Convert Waste materials into High-Profit Materials and Products
Gemite’s Technological Advantage allows to repurpose local fly ash or slag into geopolymer coatings, mortars or precast products. Using customized mix designs, most waste and inexpensive raw materials are transformed into high-performance products with significantly higher added value.
Geopolymer Technical Parameters can be Customized for Specific Application
Density Customisable from low density insulating materials, to high density concrete Chemical Resistance High resistance to acids – to resistant to combination of acids and alkali Thickness Modifiable from thin coatings to mortar and concreteAn extensive database allows us to quickly formulate customised products that satisfy variety performance parameters required, using raw materials from virtually any source.
Blast furnace slag (iron production waste) and fly ash (coal-fired power generation waste) can be converted into high profit materials using chemical activation.
Materials are 2-component or 1-component
CORRO-CHEM PROPERTIES
Formation of binding phase is much faster
Achieves a faster strength gain
May not require water curing
Parameters can be varied from high resistance to acids (both low and high concentrations) - to a range of acid and alkali
Resistant to temperatures up to 1,500o F (800o C)
Excellent fire resistance – ideal for Structural use
Inherently resistant to MIC (microbiologically induced corrosion) in sewers
Excellent sulphate attack resistance = better than cement in low pH settings
Better performance than pure calcium aluminate cements
Geopolymers bond tenaciously to concrete and even to steel
Provide better bonding results than Portland cement
Able to connect layers quickly by chemical reaction bond
High Compressive & Tensile Strengths
High Initial strength gain
Improved Durability
Density from concrete - to density of Insulating materials
Formulations for Thin Coatings, Mortar & Concrete
Abrasion resistance > surface hardened concrete
Resists heavy steel wheel traffic
Impact Resistant - even very thin section
Non-sag rheology for spray applications
High-Flow for horizontal or cast applications
Inherently resistant to MIC (microbiologically induced corrosion) in sewers
Geopolymers use large amounts of industrial Waste
Permanently prevents leaching of metals or minerals
Anti bacterial and termite resistant
Ideal for radioactive / waste encapsulation
Uses about 60% less energy
Up to 90% less CO2 than cement / concrete production
Savings due to early setting + mould / form recycling
Conventional equipment & methods to mix and place
Low Drying Shrinkage allows reduction of Control joints
Adjustable Setting Time
SEWER REHABILITATION
Geopolymer spray lining is a high performance, high strength, ultra-low porosity mortar specifically designed to rapidly form a new structural lining inside the existing sewer pipe. Application can be done regardless of pipe shape, deformities, turns, slopes and separated joints, and Corro-Chem™ bonds tenaciously to virtually any surface.
Increases Structural Integrity
High Compressive & Flexural strength
Applied by Trowel, Spray or Spin-Casting
Eliminates Infiltration of Groundwater
Suitable for deep sewers &pipes and restricted access
Easily tackles irregular shapes, bends and intrusions
STRUCTURAL STRENGTHENING
Replacing epoxy with Geopolymer greatly increases fire endurance and reduces fire hazard associated with polymeric coatings.
Geopolymer carbon fiber composite does not ignite, burn, or release smoke even after exposure to extended heat
Excellent fire resistance – retains more than 50% of its flexural strength after a fire, making it ideal for Structural Reinforcing applications
Geopolymer adheres to concrete more effectively and reliably than organic polymer materials
Lover Applied Cost than polymeric systems
Safer and User-Friendly Application
