TL;DR: In this article, the chemical reaction, mechanism, role of materials, applications, and microstructure of fly ash geopolymer cement are discussed, and the most proposed mechanism includes three stages: dissolution of Si and Al atoms from the source material through the action of hydroxide ions, transportation or orientation or condensation of precursor ions into monomers, setting or polycondensation/polymerisation of monomers into polymeric structures.

TL;DR: In this paper, the utilization of fly ash as a raw material for geopolymeric masonry brick production is discussed, and the production process and properties of fly-ash-based masonry bricks in various aspects.

TL;DR: In this paper, a review on the production of fly ash-based geopolymer bricks is presented, which is a waste material of coal firing thermal plants and its accumulation near power plants causes severe pollution problems, therefore, its utilization as a raw material for brick making will be a very beneficial solution in terms of economic and environmental aspects.

TL;DR: In this paper, the development of lightweight geopolymer bricks by using foaming agent and fly ash was dealt with by using a laboratory experiment with fix ratio of sodium silicate/sodium hydroxide solution mass ratio 2.5.

TL;DR: The contribution of ordinary Portland cement (OPC) in cement bricks production worldwide to greenhouse gas emissions is discussed in this paper, where some researchers have done their study with other materials to produce bricks, especially as a by-product material.
