The effect of Ca2+ amount and sintering temperature on mechanical properties geopolymer-brushite (GPB) binders was investigated. Brushite raw abandoned kaolinite clay thermally transformed into metakaolin were used for GPB synthesis. complete phase structural analyses performed by X-ray powder diffraction, Fourier transforms infrared spectroscopy (FT-IR). pore-filling as a consequence ions inco...

Metakaolin is a commonly used aluminosilicate material for the synthesis of geopolymer based adsorbent. However, it presents characteristics that restrict its uses such as weak rheological properties brought on by plate-like structure, processing challenges, high water demand and quick hydration reaction. Industrial waste, other hand, contains variety components potential source material. Geopo...

With the ever-increasing environmentally-driven demand for technologically advanced structural materials, geopolymer cement is fast becoming a viable alternative to traditional cements due to its proven engineering characteristics and the reduction in CO2 emitted during manufacturing (as much as 80% less CO2 emitted in manufacture, compared to ordinary Portland cement). Nevertheless, much remai...

At present, the most commonly used building material is ordinary Portland cement (OPC). However, OPC has a negative environmental effect during synthesis, with the release of significant amount of CO2 greenhouse gas. The cement industry is responsible for 5-8% of total global anthropogenic CO2 emissions. Geopolymerization is a technology capable of turning industrial wastes into strong and chem...

The emission of carbon dioxide gas from the cement manufacturing industry has raised concerns about global warming. Geopolymer concrete (GC) is gaining attention as a sustainable and environmentally friendly alternative to traditional concrete. current study focused on using local clay synthesize characterize metakaolin-based GC with varying percentages nanosilica (NS) (1.5%, 3.0%, 4.5%, 6.0%, ...
