Çalışma kapsamında iki atık malzeme olan Yüksek fırın cürufu (YFC) ve Çelikhane (ÇC) kullanılarak çimento yerine alternatif bağlayıcı elde edilmeye çalışılmaktadır. Bu amaçla, YFC ÇC farklı oranlarda geopolimer harçlar üretilmiştir. Cüruflar, %80 YFC+ %20 %60 %40 olacak şekilde ikame edilerek kullanılmıştır. Cüruflu harçların aktivasyonu için %3, %5, %7.5 %9 oranında Na2SiO3 28 günlük basınç da...

Shrinkage behavior of a geopolymer cement paste prepared from pumice-type natural pozzolan was studiedby changing parameters of chemical composition including SiO2/Na2O molar ratio of activator and total molar ratiosof Na2O/Al2O3, and H2O/Al2O3. For investigating the effect of curing conditions on shrinkage, hydrothermal curingwas also applied. The obtained results clearly revealed the governin...

The associated effect of sodium chloride and dihydrate gypsum on the mechanical performance a slag-based geopolymer activated by quicklime was investigated compressive strength, shrinkage, square circle anti-cracking tests mortar with 0.5 water–binder ratio 1:3 binder–sand ratio, as well paste soundness, powder X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microsc...

• A comparison of mechanochemically activated and conventionally geopolymer grouts. The influence slag/fly ash ratio sodium hydroxide molarity in grouts behavior. Mechanochemical activation processes effect on rheological fresh characteristics. Effect mechanochemical mechanism mechanical properties grout. In this research, a (MG) grout is adopted to activate slag, fly ash, hydroxide, silicate b...
