To maximize the utilization of red mud in geopolymers, a mud–metakaolin (RM-MK) geopolymer and mud–fly ash (RM-FA) were prepared, respectively. The effects content on compressive strength microstructure geopolymers investigated under three different curing conditions. results showed that decreased linearly with an increase content, whether at room temperature or 80 °C. Surprisingly, autoclave, ...

This investigation aimed to improve great early geopolymer mortar strengths under various parameters with binder proportions reduce the use of cement since OPC production process leads high emissions CO2. Hence, solve this problem, alternative materials were used. In research, metakaolin (MK) and ground-granulated blast-furnace slag (GGBFS) waste utilized mixed together sodium hydroxide alkalin...

This study work is related to exploring the role of connected wing walls in changing behaviour a metakaolin geopolymer wall type abutment when acted upon by all forces that are generally applied on short-span bridge. The modelling with done using STAAD Pro V8i SS6 software and loading for analysis as per IRC: 6-2016. 4-noded plate elements members, here meshed quadrilateral meshing feature. wal...

Abstract Influence of nano-glass powder on physico-mechanical properties geopolymer composite materials has been studied, in addition to studying their firing stability against high temperature from 500 up 1000 °C. For increasing mechanical, physical as well for metakaolin composites; Nano-glass was used. Alumino-silicate are kaolin, fired kaolin (metakaolin) and limestone all pass 75 µm. Mater...

Abstract—Fly ash (FA) thanks to the significant presence of SiO2 and Al2O3 as the main components is a potential raw material for geopolymers production. Mechanical activation is a method for improving FA reactivity and also the porosity of final mixture; those parameters can be analysed through sorption properties. They have direct impact on the durability of fly ash based geopolymer mortars. ...

Current ASTM standards can be used to provide a degree of characterization of geopolymeric materials, yet the researcher must be aware of differences between hydraulic and geopolymer cementitious materials. The current study assessed the applicability of available ASTM standards that analyze the insoluble content and oxide content of cementitious materials (ASTM C114 and C311), compressive stre...

Geopolymer results from the reaction of a source material that is rich in silica and alumina with alkaline liquid. It is essentially cement free concrete. This material is being studied extensively and shows promise as a greener substitute for ordinary Portland cement concrete in some applications. Research is shifting from the chemistry domain to engineering applications and commercial product...
