Life cycle assessment of geopolymer concrete: A

Alkali activated concrete (AAC) or geopolymer concrete has emerged as a promising alternative to traditional Portland cement based concrete. Geopolymer is an umbrella term which refers to a range of synthetic aluminosilicate polymeric materials, often more generically termed alkali-activated binders (AAB). Geopolymer materials can be produced from a range of natural and synthetic pozzolanic solids, activated with alkaline solutions such as sodium hydroxide and sodium silicate. Geopolymers can act as “cementless” binders to replace Portland cement pastes in concrete products. One common geopolymer material is pulverised fuel ash, PFA which is generated by power stations during the production of electricity using coal as the fuel. Finely powdered (pulverized) coal is mixed with heated air and burned. The resultant ash is transported by the exhaust gases and recovered as ‘fly ash’ with fine particles. The PFA may then be used in concrete

Experiments and Finite Element Analysis of GFRP

2018-6-1  Geopolymer concrete (GPC) utilises a binder that consists of inorganic alumino-silicate polymers synthesized from the alkaline activation of various source materials rich in alumina-silicates. These materials are usually of geological origin or are by-product materials of other processes, such as fly ash, silica fume, red mud and blast furnace slag [ 9 ].
