ALKALİ İLE AKTİVE EDİLMİŞ YÜKSEK FIRIN CÜRUFLU HİBRİT ÇİMENTO HARÇLARININ FİZİKSEL VE MEKANİK ÖZELLİKLERİNİN ÇOKLU OPTİMİZASYONU

Öz

Bu çalışmada alkali ile aktive edilmiş yüksek fırın cüruflu (YFC) hibrit harçların fiziksel ve mekanik özelliklerinin çoklu optimizasyonu araştırılmıştır. Alkali ile aktive edilmiş hibrit çimento harç (HAAC) numunelerinin üretiminde Portland çimentosu (PÇ), YFC, sodyum metasilikat (Na2SiO3), standart kum, distile su ve süperakışkanlaştırıcı kullanılmıştır. Çalışmada, seçilen etki değişkenlerine odaklanarak optimum mekanik ve fiziksel özelliklere sahip HAAC üretmek için Optimal (Kombine) Tasarım kullanılmıştır. Optimum mekanik, fiziksel ve mekanik/fiziksel özellikleri sağlayan deneme noktaları, arzu edilebilirlik fonksiyonu kullanılarak belirlenmiştir. Sonuçlar, PÇ ilavesinin mekanik özellikleri iyileştirmediğini fakat fiziksel özellikleri iyileştirdiğini göstermektedir. HAAC'larda mekanik (100% PÇ), fiziksel (60% PÇ) ve mekanik/fiziksel (60% PÇ) özellikler için arzu edilebilirlik değerleri sırasıyla 1, 1 ve 0.913 olarak elde edilmiştir. Bu nedenle, HAAC'ların kullanılabilirliği için, çevresel faktörlere dayalı olarak optimum koşulları belirlemek ve buna göre tasarım yapmak çok önemlidir.

MULTI-VARIABLE OPTIMIZATION OF PHYSICAL AND MECHANICAL PROPERTIES OF HYBRID ALKALI-ACTIVATED BLAST FURNACE SLAG MORTARS

Abstract

Multi-variable optimization of physical and mechanical properties of hybrid alkali-activated blast furnace slag (BFS) mortars was investigated. Portland cement (PC), BFS, sodium metasilicate (Na2SiO3), standard sand, distilled water, and superplasticizer were used in the production of hybrid alkali-activated cement (HAAC) mortar specimens. An Optimal (Combined) Custom Design was used in the study to produce HAAC with optimum mechanical and physical properties, focusing on selected effect variables. The run points that provided the optimum mechanical, physical, and mechanical/physical properties were determined by using the desirability function. The results show that the addition of PC to the mixture does not improve mechanical properties but it does improve physical properties. The desirability values are obtained as 1, 1, and 0.913, for the mechanical (100% PC), physical (60% PC), and mechanical/physical (60% PC) properties in HAACs, respectively. Therefore, for the usability of HAACs, it is crucial to determine the optimum conditions based on environmental factors and design accordingly.
