Global CO2 emissions are largely caused by Portland cement (PC) production. Alternative cement must be investigated to address environmental concerns. Thus, geopolymer cement concrete (GPC) is a promising candidate due to its low carbon footprint and PC-like performance. This extensive review examines geopolymer concrete (GPC) advances and appli

Oligomers form covalently bonded geopolymer networks to make geopolymer concrete. Compared to OPC concrete, its production uses less thermal energy and has a lower carbon footprint. It only needs an alkaline activator to catalyse its aluminosilicate sources like metakaolin and fly ash to produce geopolymer binder. Current research focusses on ge

Ecofriendly geopolymer concrete: a comprehensive review

Geopolymer concrete (GPC) is the most advanced concrete after OPC. GPC has many benefits, including increased strength and durability. Strong early age strength and ambient curing of GPC reduce construction time. Binders, alkali-activated solution, and curing affect GPC strength. When industrial byproducts like fly ash and ground granulated blas

Geopolymer concrete is a sustainable cement concrete alternative. Geopolymer concrete properties depend on binder material, activator solution molarity, and curing conditions. Geopolymer concrete's brittleness limits its use. Optimisation of strength and brittleness factors to synthesise high impact strength fibre reinforced geopolymer concr

Bond Stress between Steel-Reinforced Bars and Fly Ash-Based Geopolymer Concrete

Geopolymer concrete has been regarded as one of the most important green construction materials, which has been restrained in engineering applications partially due to a lack of bond studies. Reinforced concrete components' structural performance depends on the concrete-reinforcing bar bond. GPC must show understandable bond behaviour with c

This study examined the effects of ground granulated blast furnace slag (GGBFS) content, alkaline solution to binder (Al/Bi) mass ratio, sodium silicate solution to sodium hydroxide solution (SS/SH) mass ratio, and additional water to binder (Aw/Bi) mass ratio on geopolymer paste compressive strength, setting time, and workability. At 23 ±

GEOPOLYMER CONCRETE AN ECO- FRIENDLY CONSTRUCTION MATERIAL

2017

Author(s): Bashir I., Dr Sood H., Kapoor K.

Recent years have seen widespread growth in Portland cement concrete. Infrastructure growth has increased concrete demand. Durability and carbon dioxide emissions are issues with Portland cement concrete. Carbon dioxide pollution from Portland cement production and waste growth can be reduced in many ways. Indian thermal power stations produce 1

New eco-friendly construction materials alternatives to Portland cement are crucial to the industry and global climate because they reduce the use of fast-degrading natural resources and greenhouse gas emissions. In this study, Ground Granulated Blast Furnace Slag (GGBS) was used to make geopolymer cement (GPC) at ambient temperature and about 1

Effect of the reactivity of alkaline solution and metakaolin on geopolymer formation

2015

Author(s): Gharzouni A. , Joussein E., Samet B., Baklouti S., Rossignol S.

This paper examines geopolymer formation and alkaline solution reactivity and metakaolin properties. Many geopolymer samples were made from two alkaline solutions and four metakaolins to study these effects. FTIR spectroscopy and pH values were used to study geopolymer structural evolution. The mechanical properties were measured by compression.
