This paper explored the effect of sewage sludge ash (SSA) on the mechanical and microstructural properties of geopolymers based on metakaolin (MK) involving two different SiO 2 /Na 2 O molar ratios (0.8 and 1.6), two ...

This work investigates the catalytic activity of geopolymers produced using two different alkali components (sodium or potassium) and four treatment temperatures (110 to 700 °C) for the methyl transesterification of soybean ...

Use of lime as construction material is limited mainly by low initial strength. These properties can be improved by adding pozzolanic materials, but the evolution of the reaction usually needs older ages than 7 days. ...

Lattice-shaped geopolymers were successfully prepared by Direct Ink Writing to act as carriers for the immobilization of Candida rugosa lipase (CRL). The supported biocatalyst was evaluated in the hydrolysis of waste cooking ...

Geopolymers are lately being considered a group of revolutionary materials, due to their good mechanical properties, chemical stability, fire resistance and diversity of applications where they can be used. For the synthesis ...

This paper provides information about the synthesis and mechanical properties of geopolymers based on fluid catalytic cracking catalyst residue (FCC). FCC was alkali activated with solutions containing different SiO2/Na2O ...

The use of binders as an alternative to Portland cement has gained importance in recent years. Among them, geopolymeric binders, developed by the reaction between an aluminosilicate precursor and a high alkalinity solution, ...

The manufacturing of non-stochastic (lattice) scaffolds by Direct Ink Writing is attractive for catalytic fluid flow applications, as it enables the optimization of not only the desired chemically active formulation but ...
