WebOct 9, 2013 · This paper presents the mechanical and microstructural characteristics of a lightweight aggregate geopolymer concrete (LWAGC) synthesized by the alkali-activation of a fly ash source (FA) before and after being exposed to elevated temperatures, ranging from 100 to 800 °C. The results show that the LWAGC unexposed to the elevated … WebGeopolymer concrete is produced using Flyash, GGBS, Fine aggregate and coarse aggregate and Alkaline activator Solution. The two main constituents of geopolymer are 1) The source materials which are rich in Silicon (Si) and Aluminium (Al) such as Fly Ash, Rice husk, Silica Fume, GGBS etc and 2) the alkaline liquids.
WebApr 13, 2024 · Geopolymer concrete (GPC) was developed using one-part binders made from a mixture of waste clay brick (WCB) powder, fly ash, and slag in the precursor. Its suitability for use in rigid pavement construction was evaluated based on fresh properties, hardened properties, and durability characteristics. The effects of sealed and unsealed … WebApr 3, 2024 · Using fly ash in concrete reduces cracking, permeability, and bleeding, creating a dense, high-durability concrete that is resistant to sulphates and alkali-aggregate reactions. This concrete mix also requires less water and has a tendency to resist shrinking. However, using fly ash in concrete does come with potential problems.
WebApr 6, 2024 · Ordinary concrete is considered as a major construction material around the globe, but cement involved in its production contributes about 5% of world’s total carbon dioxide emissions. GPC uses alternative materials such as Fly Ash (FLA), GGBS as a replacement for cement. WebApr 30, 2024 · Flyash is a heterogeneous by-product material produced in the combustion process of coal used in power stations. Fly ash particles are almost spherical in shape which allows them to flow and blend freely in mixtures. This characteristic makes fly ash a desirable binder for concrete.
WebThe use of fluid catalytic cracking (FCC) by-products as aluminosilicate precursors in geopolymer binders has attracted significant interest from researchers in recent years owing to their high alumina and silica contents. Introduced in this study is the use of geopolymer concrete comprising FCC residue combined with fly ash as the requisite …
