...Ke-Yu Chen; Guang-Hua Lyu; Zi-Feng Wang; Yu-Qing Wang; Jin Xia The evolution of properties of a one-part fly ash-slag-based geopolymer mortar activated with sodium carbonate (Na₂CO₃, henceforth referred to as SC), sodium sulfate (Na₂SO₄ (SS...

... (CBA), which has adverse environmental impacts. However, studies have shown that CBA can be used as a replacement for NFA in concrete preparation. In this study, the fresh and mechanical properties, durability characteristics and fatigue life of pavement-quality geopolymer concrete (PQGPC) mixes...

...Datla Neeraj Varma; Suresh Prasad Singh The durability properties of geopolymer mortars prepared using different contents of slag and glass powder (GP) were examined and compared with the properties of Portland cement mortar (PCM). The slag–GP mixes were activated with a 6 M sodium hydroxide...

...Tao Wang; Xiangqian Fan; Changsheng Gao; Chiyu Qu Compared with traditional cement pastes, geopolymer pastes can effectively alleviate environmental and economic problems caused by the construction industry as they are characterised as low carbon dioxide materials, with energy reduced energy...

...Saswat Dwibedy; Suraj Kumar Parhi; Soumyaranjan Panda; Saubhagya Kumar Panigrahi Geopolymers are inorganic polymers whose formation is based on the reaction between precursors and reagents, which may be alkaline or acidic. The geopolymerisation process involves the reaction between alumina...

...Paramveer Singh; Kanish Kapoor To develop a sustainable geopolymer concrete (GC), the efficacy of using fine recycled concrete powder (FRCP) and recycled aggregates (RA) as partial replacements for fly ash (FA) and natural aggregates (NA), respectively, was investigated. The compressive strengths...

... with glass or MSM fibres had a high compressive strength (>110 MPa) and improved ductility. These specimens also had low water absorption and high electrical resistance, indicating low corrosion risk. SEM analyses showed that the MSM fibres created a denser geopolymer matrix than the glass fibres...

...Ngoc Thanh Tran; Duy Hung Nguyen; Quang Thanh Tran; Huy Viet Le; Duy-Liem Nguyen In this study, the aim is to investigate and predict the compressive strength of geopolymer concrete (GPC). The effects of curing method, curing time and concrete age on the compressive strength of GPC were evaluated...

...Sherin Khadeeja Rahman; Riyadh Al-Ameri The current study reports on the long-term structural performance of novel reinforced marine geopolymer concrete beams under accelerated weathering conditions. The study covers the flexural performance of 40 geopolymer concrete beams reinforced with basalt...

...Yong-Qian Zheng; Li-Ya Zheng; Yu-Qing Wang Geopolymer recycled brick aggregate concrete (GRC), a new type of environmentally friendly material, can reduce carbon dioxide emissions and effectively utilise construction waste. To study its basic compressive performance and stress–strain relationship...
