Extensive reuse of soda-lime waste glass in fly ash-based geopolymers [PDF]

open access: yes, 2018
The possibility of extensive incorporation of soda-lime waste glass in the synthesis of fly ash-based geopolymers was investigated. Using waste glass as silica supplier avoids the use of water glass solution as chemical activator.

Experimental research on the development of geopolymer materials using Romanian local materials [PDF]

open access: yesConstructii: Journal of Civil Engineering Research, 2018
The demand for concrete and also for the current infrastructure facilities development is experiencing worldwide exponential growth. Environmental issues associated with the production of Portland cement are very well known and therefore they are ...

Acetylsalicylic Acid Promotes Corneal Epithelium Migration by Regulating Neutrophil Extracellular Traps in Alkali Burn

open access: yesFrontiers in Immunology, 2020
Neutrophils are the first cells to migrate into the cornea in response to alkali burns, and excessive neutrophil infiltration is associated with inflammatory injury and a poorer prognosis.

Influence of size reduction of fly ash particles by grinding on the chemical properties of geopolymers [PDF]

open access: yes, 2018
Chemical properties of geopolymers were evaluated from the reduction of fly ash particle size by grinding. X-ray diffraction determined that at early curing ages new crystalline phases appear in the matrix of the geopolymer and they remain for 28 days ...

Alkali treatment influence on cellulosic fiber from Furcraea foetida leaves as potential reinforcement of polymeric composites

open access: yesJournal of Materials Research and Technology, 2022
The present study explores the potential of the alkali-treated Furcraea foetida (FF) fibers as reinforcement materials in polymeric composites. The fibers were treated and soaked for 3 h in an alkali solution of different concentrations (3, 6, 9, 12, and

Influence of local fullerene orientation on the electronic properties of A3C60 compounds

open access: yes, 2006
We have investigated sodium containing fullerene superconductors Na2AC60, A = Cs, Rb, and K, by Na-23 nuclear magnetic resonance (NMR) spectroscopy at 7.5 T in the temperature range of 10 to 400 K. Despite the structural differences from the Rb3C60 class

Management and valorisation of wastes through use in producing alkali-activated cement materials [PDF]

open access: yes, 2016
There is a growing global interest in maximising the re-use and recycling of waste, to minimise the environmental impacts associated with waste treatment and disposal.

Influence of lime, calcium silicate and portlandite on alkali activation of calcined common clays

open access: yesOpen Ceramics, 2021
The application of calcite rich common clays has marked impact on the formation of alkali-activated binders. Experiments have shown that the carbonate decomposition can be well controlled via the calcination procedure, whereby the majority of the ...

The self-trapped hole in caesium halides [PDF]

open access: yes, 1977
The equilibrium lattice configuration, electronic excitation energies and activation energies for hopping motion are calculated for a self-trapped hole in simple cubic CsCl, CsBr and CsI.
