Silica aerogel features super thermal insulating and excellent sound absorption. Although the application of silica in building materials for energy saving has been investigated recently, role particle size on geopolymer foam render can be crucial but is rarely studied. In this research, four kinds with different sizes (2–40 μm, 100–700 100–1200 700–4000 μm) are applied (GFAR) to improve insulation acoustic absorption performance. Results show that larger particles more beneficial while...
Due to its low hydraulic reactivity, ladle slag is currently underutilized with nearly 80% of annual generation either landfilled or dumped. This work investigates the joint activation LS Class F fly ash, and impact on ash geopolymer focus activation, hydrates assemblage, conversion process, thermal behavior. Results reveal that unique reaction process in alkali system shows a positive influence geopolymers. Within an alkaline rich soluble Si, initially hydrated CAH phases transform into...
As a promising alternative to alkali-activated fly ash (AAF) for high temperature application, the degradation mechanism of ash/GGBS (AAFS) under is not clear. This work investigates physicochemical properties AAFS up 800 °C and presents their synergetic influence on thermal behavior. A quantitative assessment crack developed learn cracking Results reveal that density exhibits linear relationship with ultrasonic pulse velocity. The compressive strength exhibit positive correlation before 100...
Class F Fly ash-based geopolymers are prone to various high-temperature phenomena, such as cracking, spalling, and thermal shrinkage. Here we study the effect of enriching fly ash with synthetic sodalite phase in order enhance properties formed geopolymer. The morphological changes, compositional alterations porosity, gel behaviour, on deformation material after exposure up 1000 °C investigated by a multiple-analytical approach. Results indicate that adding 5 wt% enhances considerably...
With the growing interest in foamed geopolymer manufacture, there is an increasing demand for tailoring these composites' pore structure. The binary system of two surfactants offers a possibility enhancing foam formation efficiency and stability paste, however, their effects are not well understood. influence blends on formation, size, distribution fly ash-based matrix investigated synergistic evaluated. results show that combining nonionic surfactant with anionic Sodium Dodecyl Sulfate...
In this study, an alternative utilization route for Mineral Wool Waste (MWW) as a solid precursor artificial aggregate manufacturing is proposed. The process parameters including alkali activation (Na or K) and curing regimes are investigated. Room high-temperature (1000 °C) characterizations performed on the plain aggregates when incorporated in geopolymer composite. results reveal that with optimum pre-curing regime at room temperature 3 days, particle density ranging from 1960 to 2090...
