Bu çalışmada atık cam tozu ile üretilen geopolimer harçların fiziksel ve mekanik özelliklerine kalsiyum alüminat çimentosunun farklı kür koşullarında etkisi araştırılmıştır. Bu amaçla atık cam tozu ve %5, %10, %15, %20 ve %25 oranında kalsiyum alüminat çimentoları (Isıdaç40 ve Refro50) içeren onbir farklı karışıma sahip geopolimer harçlar üretilmiştir. Harçlarda aktivatör olarak sodyum silikat kullanılmıştır. Üretilen geopolimer harçlar 24 saat 90°C etüv ve 24 saat hava + 24 saat 90°C etüv olmak üzere 2 farklı küre tabi tutulmuştur. Harçlar üzerinde yayılma tablası, su emme-boşluk oranı, eğilme ve basınç dayanımı deneyleri gerçekleştirilmiştir. En yüksek 7 ve 28 günlük basınç dayanım değerleri hava+etüv küründe %5 Isıdaç40 tipi çimento ile üretilen harçlarda sırasıyla 24,2 MPa ve 25,5 MPa olarak elde edilmiştir.
This study has studied the effects of geopolymers produced with waste glass powder on the physical and mechanical properties of calcium aluminum cement in different curved conditions. For this purpose, geopolymers with eleven different mixture of waste glass powder and 5% of 10% of 15% of 20% and 25% of calcium aluminum cement (Heating40 and Refro50) were produced. Sodium silicate is used as an activator. The geopolymers produced were subjected to 2 different globes, 24 hours 90°C and 24 hours air + 24 hours 90°C. The spread table on the shells, the water absorption-discovery ratio, inclination and pressure resistance experiments have been carried out. The highest 7 and 28 day pressure resistance values were obtained in air+tune currents with 5% heating40-type cement, respectively, at 24.2 MPa and 25.5 MPa.
In this study, the physical and mechanical properties of geopolymer mortars made with waste glass powder under different curing conditions have been investigated. For this purpose, eleven different geopolymer mortars containing waste glass powder and 5%, 10%, 15%, 20% and 25% calcium aluminate cement (Isıdaç40, and Refro50) were produced. Sodium silicate was used as activator in the mortars. The produced geopolymer mortars were subjected to two different curing conditions in an oven at 90° C for 24 hours and in the air for 24 hours + at 90 ° C for 24 hours in the oven. Flow table, water absorption and porosity, flexural strength, and compressive strength tests were performed on the mortars. The highest 7 and 28 days compressive strengths were obtained in mortars produced with 5% Isıdaç40 type cement in the air for 24 hours, respectively 24.2 MPa and 25.5 MPa.
