Analysis and reproduction of geopolymer concrete
Geopolymers are inorganic polymers based on aluminosilicates that are produced from synthesizing pozzolanic compounds or aluminosilicate source materials with highly alkaline solutions. Geopolymer concrete is a stronger, more durable and more environmentally friendly alternative to ordinary …

Flexural Behaviour of Geopolymer Concrete T-beams Reinforced with FRP or Hybrid FRP/Steel bars
… be replaced with binders that emit less CO2. Geopolymer binder is an alternative to Portland cement that does not emit CO2 during manufacture. GPC reinforced with any material should provide a building system that is durable, economical, and ecologically friendly. The main aim of this study is …

Performance of geopolymer concrete subjected to mineral acid corrosion and related to microbially-induced corrosion (MIC) of concrete in sewers
… erosion-corrosion exposure condition for some concrete mixes. In this study, the static HCl test and the dynamic HCl test were used to measure the resistance of concrete mixes under the static corrosion exposure condition and erosion-corrosion exposure condition respectively. However, concretes …

Development and performance of class F fly ash based geopolymer concretes against sulphuric acid attack
Geopolymer concretes synthesised from composite class F fly ashes and a mixed alkaline activator were optimised by use of Taguchi orthogonal design method. The optimised mix achieved a compressive strength at the age of 28 days of 70 and 58 MPa after initial curing at 70°C for 12 hours and at 23°C …

Nucleation seeding in metakaolin geopolymers
Geopolymers are a class of amorphous, aluminosilicate-based binders proposed as an alternative to the cement binders used commonly in the construction industry. One of the main advantages of using geopolymer concrete is the fact that waste materials like fly ash are used as precursors for its …
