Geopolymer concrete: A review of some recent developments
Graphical abstract Conversion of fly ash into geopolymers/concrete. Display Omitted
Highlights An overview of geopolymer is presented alongwith its processing parameters. The hardened properties and durability of geopolymer concrete are discussed. The design guidelines for OPC concrete are applicable to geopolymer concrete also. Geopolymeric building products developed at CSIR-CBRI are highlighted. Ambient cured single component geopolymer may enhance its wider use in the field.
Abstract An overview of advances in geopolymers formed by the alkaline activation of aluminosilicates is presented alongwith opportunities for their use in building construction. The properties of mortars/concrete made from geopolymeric binders are discussed with respect to fresh and hardened states, interfacial transition zone between aggregate and geopolymer, bond with steel reinforcing bars and resistance to elevated temperature. The durability of geopolymer pastes and concrete is highlighted in terms of their deterioration in various aggressive environments. R&D works carried out on heat and ambient cured geopolymers at CSIR-CBRI are briefly outlined alongwith the product developments. Research findings revealed that geopolymer concrete exhibited comparative properties to that of OPC concrete which has potential to be used in civil engineering applications.
