“…A high Si-OH group in calcium silicate materials promotes the HA precipitation through the increased nucleation sites [15]. For aluminosilicate/inorganic polymer, the studies on bioactive functional group on its surface were presented for both in vivo and in vitro studies [9][10][11][12]16]. However in this system, the high alkalinity condition was not conducive for the existence of HA and the cell [17].…”

In this study, calcined kaolin-white Portland cement geopolymer was investigated for use as biomaterial. Sodium hydroxide and sodium silicate were used as activators. In vitro test was performed with simulated body fluid (SBF) for bioactivity characterization. The formation of hydroxyapatite bio-layer on the 28-day soaked samples surface was tested using SEM, EDS and XRD analyses. The results showed that the morphology of hydroxyapatite was affected by the source material composition, alkali concentration and curing temperature. The calcined kaolin-white Portland cement geopolymer with relatively high compressive strength could be fabricated for use as biomaterial. The mix with 50% white Portland cement and 50% calcined kaolin had 28-day compressive strength of 59.0MPa and the hydroxyapatite bio-layer on the 28-day soaked sample surface was clearly evident.

“…In the literature, no specific studies on the cytotoxicity of geopolymers containing waste were found; authors are aware of papers published only on cement for dental application [5,6], glasses [7], materials for shore protection [8], and traditional building materials [9]. Moreover, some studies [10,11] are reported which evaluate the potential application of geopolymers in the biomedical field. However, their clinical use is hindered by Al release.…”

Addition of WEEE Glass to Metakaolin-Based Geopolymeric Binder: A Cytotoxicity Study

2017

View full text Add to dashboard Cite

Waste Electrical and Electronic Equipment (WEEE) types of glass, including Cathode Ray Tube (CRT) glass, are now separately collected in European Union 28 (EU28) zone. Due to the high level of Pb and Ba in their compositions, this type of waste finds its way to the disposal. In the present research, a geopolymer matrix based on metakaolin is used to blend in fine powder panel and funnel glass from personal computer (PC) and television (TV) monitors. Such waste glass, which cannot be directed to glass melting furnaces, is safely incorporated into a geopolymer matrix. The consolidation of the geopolymeric matrix containing the waste glass was followed by pH and conductibility up to 28 days of curing. Scanning electron microscope equipped with energy dispersive spectroscopy (SEM/EDS) was used to obtain information on the microstructure of the consolidated products. Cytotoxicity tests helped the environmental evaluation of these materials.

“…Recently, biocompatible metakaolin-aluminosilicate materials have been tested both in vivo [17][18][19] and in vitro [20][21][22][23] . For implant applications 24 , geopolymers have been shown to be bioactive with low ion leakage, although the possible leaching of aluminium can result in toxicity 21 .…”

This paper reports that surface treatment with CaCl 2 enhances the bioactivity of a calcined kaolin geopolymer. Calcined kaolin, NaOH solution, sodium silicate solution, and heat curing were used to form geopolymer pastes. A soaked-treatment method was applied to the geopolymer samples using CaCl 2 solution as the ion exchange agent. The bioactivity of the material was determined by the simulated body fluid (SBF) in vitro testing method. Scanning electron microscope images showed a dense apatite formation on the treated geopolymer surface after SBF immersion for only 3 days. The CaCl 2 treatment promoted compressive strength and enhanced bioactivity by accelerating apatite precipitation and slowing down the rise in pH.
