Farklı Tane Boyutuna Sahip Afşin-Elbistan Uçucu Külünün Geopolimer Hammaddesi Olarak Kullanımı

It is aimed to be used as a raw material in the production of geopolymer mortars containing Afşin - Elbistan fly ash with high rate calcium oxide two different grain sizes. In design these mortar mixtures, activator/binder ratio was kept constant 0.55, water/binder 0.50 and sand/ binder 0.30. Sodium silicate (SS) sodium hydroxide (SH) were together activators. SS/SH 1 1.5, molarity 10 14 M, curing temperature 60 ºC 90 for 24 hours. The fresh hardened unit weight, ultrasonic velocity compressive strength properties samples investigated. addition, changes microstructure investigated by thermogravimetric analysis X-ray diffraction analysis. highest 14GF0.55/1.5-90 (14M SH, use ground ash, 1.5 temperature) given this value 10.30 MPa. increase from SS / SH increased mechanical due geopolymerization reactions. Also, UPV results have denser structure. These are also supported XRD TGA
